Subject: [ITK-users] New Submission: Performance Benchmarking the Insight
	Toolkit
Message-ID: <20160701203404.F35403D6207E@insight-journal.org>

Hello,

A new submission has been added to the Insight Journal.

Title: Performance Benchmarking the Insight Toolkit
Authors: McCormick M., Kang H.J., Barre S.
Abstract: This document describes a module for the Insight Toolkit (ITK) to assist in performance
benchmarking and a suite of benchmarks for the toolkit. These resources provide metrics to quantify
software computational performance. This is a pre-requisite to improve performance either through
algorithmic advancements or better utilization of hardware resources.
Computational performance is quantified by reducing factors that confound timing measurements and
by estimating measurement variance. New classes are presented that increase operating system process
priority to minimize the impact of other processes running on the system. System hardware characteristics
are extracted and displayed. The influence of hard disk input/output on runtime measurements is
removed in the suite of benchmarks. Additionally, the number of threads used by each benchmark can be
specified. These benchmarks consist of common analysis pipelines and run on 3D magnetic resonance
brain image data so realistic performance is quantified. Benchmarks can be executed with multiple iterations,
and timing statistics are recorded in tab separated value (.tsv) files, which are easily stored or
processed for further analysis and visualization.
This paper is accompanied with the source code, input data, parameters and output data that the authors
used for validating the algorithm described in this paper. This adheres to the fundamental principle
that scientific publications must facilitate reproducibility of the reported results.

	morphology image filters for ITK
Message-ID: <20160701212944.EF55F3D62059@insight-journal.org>

Hello,

A new submission has been added to the Insight Journal.

Title: OpenCL accelerated GPU binary morphology image filters for ITK
Authors: Bardosi Z.
Abstract: Binary morphological operations are fundamental tools in image processing but the processing time scales with the number of pixels thus making them expensive operations on the CPU for larger 3D datasets that typically appear in medical imaging. Since erosion and dilatation are special neighborhood operators, each pixel in the output depends only on the neighborhood region which makes them fit for massive GPU parallelization. This document introduces a new ITK module that implements generic (OpenCL based) GPU accelerated binary morphology image filters for erosion and dilatation. The filter can be executed within the standard ITKGPU pipeline.

	SimpleITK+Python
Message-ID: <CAHWMK+iAYci1JwrNDhftkahmcnMP=AjZtpO5=RF7_fj44L2iAw@mail.gmail.com>

Hello all,

Is there a way to read an image with SimpleITK+Python from a file object
(as opposed to a string/filename)? I cannot find anything in the Doxygen or
otherwise to do this.

Here is a toy example:

    import cStringIO
    import SimpleITK as sitk
    dcmfn="test.dcm"
    with open(dcmfn,'rb') as data:
        body = data.read()
        strio=cStringIO.StringIO(body)
        img=sitk.ReadImage(strio)
        strio.close()

Subject: [ITK-users] LabelStatisticsImageFilter in 3D
Message-ID: <6ECF75BD-4C2B-4FE4-BD6D-FFFDC7A414BD@gmail.com>

Hi

Using SimpleITK I'm trying to get statistics for a grayscale image segmentation for which I have a binary mask.  Both image and mask are 3D volumes

I have converted my binary mask to a Label map and then tried to apply the LabelStatisticsImageFilter, however I get the following exception:

Pixel type: 32-bit float is not supported in 3D

I've tried casting the intensity image to unsigned int, Float 64 etc... none of them work.  It seems to be the 3D that is the issue.  Is this filter defined for 3D images?  There is nothing I have found in the documentation/source to suggest not.

Thanks

Hi guys

I have to register two 3D images of teeth (screenshots attached).
I tested several approaches, such as: affine registration, rigid
registration,
mattes and mean square metric, etc.
When I use moments centering I get an error (Too many samples map outside
moving
image buffer)   and when I use geometric centering I do not get error, but
the result (resampler)
is exactly the same moving image. Any sugestions

Thank you so much

 Dear Sir or Madam.

 I am a student in Biomedical Engineering at the Silesian University of 
 Technology. During my studies I worked with ITK and SimpleITK in C#. I 
 want to use them in my current project, but I have an important 
 question. After loading and processing a series of .dcm files I lost 
 information about the patient and study to which they belong, and that 
 they belong to one series. How can I keep this information?

 I will be very grateful for any answer.

 Best regards.

 Peter.

Hi Oscar,

The error you are receiving means that your images don't overlap with the initial transformation in the physical space. 
You have to set a better transformation initialization.
You should take a look to the itk CenteredTransformInitializer ( https://itk.org/Doxygen/html/classitk_1_1CenteredTransformInitializer.html#a3284b1aabf2690889aa7435676fc7893 ), or the versor version of it, if you're using a transform with versor for rotation.
This will help setting a good starting position.

HTH,

Tim

Hello,

SimpleITK does not currently support this low level interface. I am not aware of an ITK ImageIO that directly support reading am image from a C FILE object either.

You may find a lower level IO library such as GDCM or jpeg which can support this type of feature, but I have not tried it myself.

HTH,
Brad

Hi Piotr,

if you want to carry over metadata from input image to output image, you
should save the metadata dictionary in a way similar to this:

itk::MetaDataDictionary metadata;

template< typename TImage >
itk::SmartPointer<TImage> readImage(std::string fileName)
{
    typedef itk::ImageFileReader<TImage> ReaderType;
    typename ReaderType::Pointer reader = ReaderType::New();
    reader->SetFileName(fileName.c_str());
    try
    {
        reader->Update();
        metadata = reader->GetMetaDataDictionary();
        return reader->GetOutput();
    }
    catch (itk::ExceptionObject & error)
    {
        std::cerr << "Error: " << error << std::endl;
        return NULL;
    }
}

template< typename TImage >
void writeImage(itk::SmartPointer<TImage> image, std::string fileName)
{
    image->SetMetaDataDictionary(metadata); //full metadata
    typedef itk::ImageFileWriter<TImage> WriterType;
    typename WriterType::Pointer writer = WriterType::New();
    writer->SetFileName(fileName.c_str());
    writer->SetInput(image);
    try
    {
        writer->Update();
    }
    catch (itk::ExceptionObject & error)
    {
        std::cerr << "Error: " << error << std::endl;

Hi Mathew,

As I haven?t seen your code I cannot pinpoint the issue, but it is not the
dimension of the image.

The following SimpleITK code does what I believe you are asking for (image
is available here - https://midas3.kitware.com/midas/item/317034):

import SimpleITK as sitk

image = sitk.ReadImage("training_001_ct.mha")

# HU values for bone are 700 and up
segmented_image = image>700

# segmented label for the threshold operation is 1 (0 for everything else).
# the LabelIntensityStatisticsImageFilter also works with multiple labels
and not just a binary segmentation.
segmented_label = 1

lisf = sitk.LabelIntensityStatisticsImageFilter()
lisf.Execute(segmented_image, image)

print("mean HU value: {0:.2f}".format(lisf.GetMean(segmented_label)))

     hope this helped

             Ziv

Ziv: thanks for the reply.

I'm using the R wrapped version of SimpleITK

I've run the equivalent of your example:

library('SimpleITK')
image = ReadImage('training_001_ct.mha')

segmented_image = image>700

lisf = LabelIntensityStatisticsImageFilter()
lisf$Execute(segmented_image, image)

Unfortunately I'm getting the same error as for my own scripts:

Warning message:
In f(...) :
  Exception thrown in SimpleITK Show: /ITK/SITK/Source-Current/Build-290516/ITK-prefix/include/ITK-4.10/itkImageFileWriter.hxx:290:
itk::ERROR: ImageFileWriter(0x10c05cbc0): Largest possible region does not fully contain requested paste IO regionPaste IO region: ImageIORegion (0x7fff5fbf6cd8)
  Dimension: 2
  Index: 0 0 
  Size: 0 0 
Largest possible region: ImageRegion (0x7fff5fbf6d70)
  Dimension: 2
  Index: [0, 0]
  Size: [0, 0]

I have a feeling that this is a problem with the LabelIntensityStatisticsImageFilter being templated over 2D and 3D images and when it is instantiated it is defaulting to the 2D?  Previously using Python wrapped ITK (i.e. not SimpleITK) when I declared these filters I would give it a 2D or 3D image type but this is not possible in SimpleITK.

However, if this is working for you in Python-SimpleITK maybe it is an issue peculiar to the R wrapping?

Any further suggestions would be appreciated

Cheers

Hello,

Did you compile R SimpleITK from a very recent version of the SimpleITK master branch from git?

There have been a lot of improvements for the R wrapping, and required improvement with SWIG too. This looks like an problem that has been fixed related R reference counting. 

SimpleITK is smart enough to know when to call the 3D or 2D version of a filter. It also knows the pixel types of the inputs and calls the correct template combinations for the ITK filter automatically. When the filter is not instantiated with the pixel types passed to it will give an error message as the original poster of this thread got.

HTH,
Brad

Hi

Compiled from a git around two months ago.

In fact, though the error report suggests a fatal problem, the code I
posted does work in as much as I can use the filter to get the label
statistics.  I don't know if the warning that comes up impacts on the
filter function - I have not found a problem thus far.  When I get a
chance I'll recompile a more recent version and check the errors
again.

Thanks

Subject: [ITK-users] R-SimpleITK memory management
Message-ID: <CAC5Ld0CH-8pOQJrH+-=AoUatYmVn7+A-+Murw0hEcoPdZd238w@mail.gmail.com>

I'm processing a large number of CT scans using R wrapped SimpleITK
(some filtering and then registration before a segmentation).   I'm
running R within RStudio on OS X 10.11

I'm running into memory problems with long processing runs.  Though in
the R loops I reassign new images to the same R variable the
underlying C++ objects do not seem to get deleted but accumulate on
each loop - I can see steadily rising memory usage in Activity Monitor
until R/RStudio crashes.  I have tried explicitly deleting the
temporary images during each loop and calling the R garbage collector
(gc()), but it doesn't seem to have an effect.  If I restart the R
session then the memory is cleared.

My understanding was that the C++ objects would get garbage collected
once all pointers are removed but this doesn't seem to happen.  Is
there a method to explicitly delete the C++ image objects so I can
manage the memory usage myself?

Cheers

This is an issue with the fact that some filters return a zero sized image
for some method calls. The default behavior of R is to attempt to display
this variable (showing a zero size image crashes). You have two options
either assign to a dummy variable or wrap with ?invisible?. Following code
works in R:

library(SimpleITK)

image <- ReadImage("training_001_ct.mha")
segmented_image <- image>700
segmented_label <- 1
lisf <- LabelIntensityStatisticsImageFilter()
ignore_me <- lisf$Execute(segmented_image, image)
# or
invisible(lisf$Execute(segmented_image, image))

cat(lisf$GetMean(segmented_label))
cat(ignore_me$GetSize())


Finally, with regard to building and installing SimpleITK, we now have a
one liner (assuming you have git, Cmake and a working compiler and have
devtools installed in your R environment):

devtools::install_github("SimpleITK/SimpleITKRInstaller",
args=c('--configure-vars="MAKEJ=6"'))


Please set the number of cores according to what you have (we used 6 for
the example).

       regards
          Ziv

Hi Mathew,

Can you provide a concise example so that we can recreate the problem? I
tried the trivial thing with the code we were previously discussing, just
repeatedly running it in a loop and the memory useage is as expected,
doesn?t change after initial run, code below:

library(SimpleITK)
library(pryr)

for(i in 1:100)
{
  print(mem_used())
  image <- ReadImage("training_001_ct.mha")
  segmented_image <- image>700
  segmented_label <- 1
  lisf <- LabelIntensityStatisticsImageFilter()
  invisible(lisf$Execute(segmented_image, image))
  print(mem_used())
}

When I ran this in R studio the memory usage was higher, but still
consistent. Apparently R studio also keeps a reference to every object
created on the command line (Hadly Wickham?s book on Advanced R, memory
management http://adv-r.had.co.nz/memory.html).

Hi,

You may want to investigate the open source, ITK-based ITK-SNAP project,
which has similiar functionality.

HTH,

Hi Abdelkhalek,

Slicer <https://www.slicer.org/>'s editor module has a graph-cut "effect"
which is quite similar to what the video shows.

Hi D?enan,

thank you for your help and for this example. Unfortunately, I have not
found method GetMetaDataDictionary() in SimpleITK in C# (I found only
GetMetaDataKeys() and GetMetaData(string key)). Also, I have not found a
method SetMetaDataDictionary or any other that allows me to assign DICOM
tags.

My short piece of code looks like this:

static public void ReadImage()
        {
            sitk.ImageFileReader reader = new sitk.ImageFileReader();
            reader.SetFileName(@".\DICOM_TEST\original.dcm");
            var image = reader.Execute();

            sitk.ImageFileWriter writer = new sitk.ImageFileWriter();
            writer.SetFileName(@".\DICOM_TEST\modified.dcm");
            writer.Execute(image);
        }

Another problem is that your example describes only loading and saving a
single .dcm file. What if I have to process a whole series of files using
sitk.ImageSeriesReader and sitk.ImageSeriesWriter?

Regards,

Peter.

Hi Piotr,

instead of ImageReader->GetMetaDataDictionary() call
ImageSeriesReader->GetMetaDataDictionary(). Also, the image format you are
writing to needs to be able to support metadata (e.g. .mha, .nrrd, DICOM),
otherwise the metadata is lost (.nii, .jpg, .bmp etc).

But for writing DICOM, the process might be somewhat different from what I
described in the first email. Definitely different if you want metadata
copied slice for slice from input to output - in this case some metadata
needs to be changed anyway, such as flag that this is a derived image and
not an original image coming out of a scanner.

I suppose that MetaDataDictionary class is not wrapped. You can then loop
through all the keys and copy them and their content one by one.

Regards

Subject: [ITK-users] Lost Patient, Study and Series DICOM tags

Hello Again

I found the information, that in SimpleITK the MetaDataDictionary interface
is only part of the Image class. Currently it provides a read only
interface, with the GetMetaDataKeys(), and GetMetaData(key) methods. This
get method only returns the type of data in the dictionary converted to a
string.

The required method would be Image::SetMetaData(key,value). But
unfortunately I do not see this method, so I think that this is still not
implemented. The only what I need is to keep information that my files
belong to one series of images, which belongs to one patient and study (
not necessarily the same study or series as the original).

Regards.

Peter.

If SimpleITK does not provide write access to meta-data dictionary, you can
indicate patient, study and series in the filename by specially formatting
it.

Hopefully Brad can provide more useful advice.

Hello Peter,

We are actually working on adding the set method for the upcoming release, which will be out shortly. One issue that we do want to point out, which likely you are aware of but just in case, you have to indicate in the Image Type tag ( (0008,0008) that this is a derived image. Please see the DICOM standard (http://dicom.nema.org/medical/dicom/current/output/pdf/part03.pdf), section  C.7.6.1.1.2 for the details.

        regards
             Ziv

Subject: Re: [ITK-users] Lost Patient, Study and Series DICOM tags

Hello Again

I found the information, that in SimpleITK the MetaDataDictionary interface is only part of the Image class. Currently it provides a read only interface, with the GetMetaDataKeys(), and GetMetaData(key) methods. This get method only returns the type of data in the dictionary converted to a string.

The required method would be Image::SetMetaData(key,value). But unfortunately I do not see this method, so I think that this is still not implemented. The only what I need is to keep information that my files belong to one series of images, which belongs to one patient and study ( not necessarily the same study or series as the original).

Regards.

Peter.


2016-07-07 14:45 GMT+02:00 D?enan Zuki? <dzenanz at gmail.com<mailto:dzenanz at gmail.com>>:
Hi Piotr,

instead of ImageReader->GetMetaDataDictionary() call ImageSeriesReader->GetMetaDataDictionary(). Also, the image format you are writing to needs to be able to support metadata (e.g. .mha, .nrrd, DICOM), otherwise the metadata is lost (.nii, .jpg, .bmp etc).

But for writing DICOM, the process might be somewhat different from what I described in the first email. Definitely different if you want metadata copied slice for slice from input to output - in this case some metadata needs to be changed anyway, such as flag that this is a derived image and not an original image coming out of a scanner.

I suppose that MetaDataDictionary class is not wrapped. You can then loop through all the keys and copy them and their content one by one.

Regards

Hi D?enan,

thank you for your help and for this example. Unfortunately, I have not found method GetMetaDataDictionary() in SimpleITK in C# (I found only GetMetaDataKeys() and GetMetaData(string key)). Also, I have not found a method SetMetaDataDictionary or any other that allows me to assign DICOM tags.

My short piece of code looks like this:

static public void ReadImage()
        {
            sitk.ImageFileReader reader = new sitk.ImageFileReader();
            reader.SetFileName(@".\DICOM_TEST\original.dcm");
            var image = reader.Execute();

            sitk.ImageFileWriter writer = new sitk.ImageFileWriter();
            writer.SetFileName(@".\DICOM_TEST\modified.dcm");
            writer.Execute(image);
        }

Another problem is that your example describesonly loading and saving a single .dcm file.What if I have to process a whole series of files using sitk.ImageSeriesReader and sitk.ImageSeriesWriter?

Regards,

Peter.

Hi Piotr,

if you want to carry over metadata from input image to output image, you should save the metadata dictionary in a way similar to this:

itk::MetaDataDictionary metadata;

template< typename TImage >
itk::SmartPointer<TImage> readImage(std::string fileName)
{
    typedef itk::ImageFileReader<TImage> ReaderType;
    typename ReaderType::Pointer reader = ReaderType::New();
    reader->SetFileName(fileName.c_str());
    try
    {
        reader->Update();
        metadata = reader->GetMetaDataDictionary();
        return reader->GetOutput();
    }
    catch (itk::ExceptionObject & error)
    {
        std::cerr << "Error: " << error << std::endl;
        return NULL;
    }
}

template< typename TImage >
void writeImage(itk::SmartPointer<TImage> image, std::string fileName)
{
    image->SetMetaDataDictionary(metadata); //full metadata
    typedef itk::ImageFileWriter<TImage> WriterType;
    typename WriterType::Pointer writer = WriterType::New();
    writer->SetFileName(fileName.c_str());
    writer->SetInput(image);
    try
    {
        writer->Update();
    }
    catch (itk::ExceptionObject & error)
    {
        std::cerr << "Error: " << error << std::endl;
    }
}

Dear Sir or Madam.

I am a student in Biomedical Engineering at the Silesian University of Technology. During my studies I worked with ITK and SimpleITK in C#. I want to use them in my current project, but I have an important question. After loading and processing a series of .dcm files I lost information about the patient and study to which they belong, and that they belong to one series. How can I keep this information?

I will be very grateful for any answer.

Best regards.

I know that GDCM library (or its elements) is used in some cases in ITK. If
SimpleITK does not provide write access to dicom tags whether is it
possible to use GDCM wrapped in C# to do this? I can imagine a scenario in
which I'll use SimpleITK to process image, and GDCM to replace specified
tags.

Is it possible? If so, I would ask for help person skilled in using GDCM in
C#. Are there any examples of how to do such a thing?

Hello,

We have just merged the topic which adds the ?SetMetaData? method to the SimpleITK Image interface into the ?next? development branch of SimpleITK [1]. We expect for this to shortly be merged into the master branch after nightly testing. We are also creating an example which uses it for writing a modified DICOM file.

There should be nightly binaries that follow shortly there after for CSharp [2]. This may meet your needs.

Directly using GDCM is a sensible way to go for more control over DICOM IO. I have not done what you propose, but I expect it is possible. You would likely need some lower level buffer access as is done here[3].

HTH,
Brad

Subject: [ITK-users] SimpleITK landmark based initialisation (and image
	visualisation)
Message-ID: <21BECCEC-1354-4E9A-B08F-D36BFE535407@gmail.com>

Hi,

I was thinking of adding a manual landmark based initialisation to my image registration method, as the automatic initialiser does not reliably work in my current application. I?m registering correlative microscopy images with very large shift and rotation between moving and fixed images ? usually the moving image also covers only a small part of the area shown in the fixed image. By specifying the initial offset and rotation manually, registration works nicely, but this is a bit cumbersome, because I have to figure out the approximate offsets first.

The problem is that I do not seem to have the sitk.LandmarkBasedTransformInitializer() available in my SimpleITK version. It was used in the notebook http://insightsoftwareconsortium.github.io/SimpleITK-Notebooks/67_Registration_Semiautomatic_Homework.html. I have SimpleITK 0.9.1 (Compiled Sep 28 2015) that I have installed on Anaconda according to the Wiki instructions. I am using Python 2.7. Would I possibly need some other version of SimpleITK? How could I get it? 

Alternatively, is there some other simple method for calculating a spatial transformation from control point pairs in SimpleITK? I can of course do that in Numpy, but I wouldn?t like to overly complicate things.

Another question, in the notebook above you are using a visualisation module named ?gui" to show nice interactive plots, from which it is possible to make landmark selections as well. Is that by chance publicly available somewhere?  

Best,

Sami

Hello Sami,

We are just about to release the latest version of SimpleITK which includes the LandmarkBasedTransformInitializer. This will happen in the next couple of weeks.

For an immediate solution, you can build the toolkit?s master branch for anaconda using the conda recipe found on my github:

git clone https://github.com/zivy/conda-recipes.git
cd conda-recipes
git checkout simpleitkMaster
cd python
conda build simpleitk

Then just install the package you built. This build process is for people who want to stay on the cutting edge, in between official releases (the master branch is our stable branch so you should be fine).

     regards
              Ziv

Hello Tim,

Thank you for your helpful email and sorry for late reply.

Yes, that's right. The size of resampled imageC should be 256x68x256 and
imageC should be rotated -pi/2 around the X axis.
Now, my first question is: Can I use the direction of imageA as
the OutputDirection instead of using Euler3DTransform? Something like this:

# Direction of imageA: (1.0, 0.0, 0.0, 0.0, 1.0, 0.0, 0.0, 0.0, 1.0)
# Direction of imageC: (1.0, 0.0, 0.0, 0.0, -0.0, 1.0, 0.0, -1.0, -0.0)
resample = sitk.ResampleImageFilter()
resample.SetTransform(sitk.Transform(3, sitk.sitkIdentity))
resample.SetReferenceImage(imageC)
resample.SetOutputDirection(imageA.GetDirection())
resample.SetOutputOrigin(imageA.GetOrigin())
spacingCA = [spacingC[0],spacingC[2],spacingC[1]]
resample.SetOutputSpacing(spacingCA)
sizeC = imageC.GetSize()
sizeCA = [sizeC[0], sizeC[2], sizeC[1]]
resample.SetSize(sizeCA)
imageCA=resample.Execute(imageC)
sitk.Show(imageCA)

Second, I think I haven't set the correct OutputOrigin for the resampled
image because when I compare imageCA with the axial view of imageC
(calculated by ImageJ > Stacks> Orthogonal Views), it seems that the
resulted imageCA is the translated version of the correct axial view.

I have read the ITK guide chapter 2.9 about transformation and resampling
processes but it is still vague to me how one should calculate/select the
correct origin for the output image. I would be thankful if you could refer
me to any other resources that could be helpful to me in this regard.

Thank you in advance.

Best regards,
Sara

Hi Sara,

The origin of an image is the point in world coordinates where the image "start" (from lower indexes to higher ones), not to be confused with the origin of the reference frame, which is [0,0,0]. When dealing with geometry, a drawing is often helpful to know what happens to the image origin during transformation.

And yes, you could do it through direction modification, that's just a bit more complicated.
Since modifing direction means transforming the reference frame, you have to compute where and which point will be the new origin of the imageC.

Sticking with the previous hypothesis on imageC position, the "true" origin of imageC (origin of imageCA) is the point:
-last in the original Y imageC direction
-first in the original X imageC direction
-first in the original Z imageC direction

So if the original origin of imageC is [0,0,0], this point will be [0,SizeC[1]*SpacingC[1],0].
Then this "true" origin will be modified by the rotation of the frame. In your case , -pi/2, giving [0,0,-SizeC[1]*SpacingC[1]].
Put this as the output origin and you should be fine.
Of course, is the original origin of imageC isn't [0,0,0], you should compute the new point accordingly.

For general matters, it should be noted that this works because the default rotation center is also the reference frame origin (i.e. [0,0,0])

HTH,

Tim

Hi Ibraheem,

the signature
<https://itk.org/Doxygen/html/classitk_1_1MutualInformationImageToImageMetric.html>
of GetValue method is:
MeasureType GetValue (const ParametersType &parameters) const override;
which means that you need to give transform parameters to get a value. What
you might want is create an identity transform and pass that in.

Regards,
D?enan

there is no "advantage" to seeds, it is how confidence connected filter
operates. It finds all voxels which are connected to the provided seeds
with a certain confidence. So seeds are starting points.

D?enan

Hi Meikolin,

it is not clear to me what your problem is. Can you give some images (what
you get, what you want, where you put the seeds) and explain a bit more
what you did code-wise? Otherwise I would have to guess.

Regards,
D?enan

Subject: [ITK-users] region of interest size problem
Message-ID: <57895E0A.7010108@gmail.com>

Hi Guys

I am trying to extract a region of interest (ROI) from a 3D tomography
I am using the filter  "itkRegionOfInterestImageFilter.h". The issue is
that the filter changes the original size of the input image.
According the documentation, the output image has the same
dimension of the input image. But size of the output image
is the size of the selected region (ROI).
My code is based on this example:
https://itk.org/Wiki/ITK/Examples/ImageProcessing/RegionOfInterestImageFilter

Thank you for your suggestions
Oscar

Hi Oscar,

the output dimension is the same: 3D input produces 3D output, 2D input
produces 2D output etc. But the point of RoI filter is to get an image
which is only a part of the input image, and in that respect the filter is
working correctly. What did you expect to happen? If you want only part of
the image be processed, set its RequestedRegion to something smaller than
LargestPossibleRegion.

Regards,
D?enan

Subject: [ITK-users] Deformable registration question
Message-ID: <1468832456487.30276@sphic.org.cn>

Hi all,


I have two questions.

1) Has itk::BSplineTransformInitializer been wrapped to python-supported ITK?

2) Which deformable registration algorithms in ITK can deal with multi-modal image registration such as CT-MR registration?

Thanks.



Regards,


Zhuangming Shen

Hi Shen,

2) for multi-modal registration you need to use one variant of mutual
information registration metric. All the other parts of the registration
framework should be applicable.

There is a paper
<http://www.insight-journal.org/download/viewpdf/859/4/download> which goes
along with the source code, which give more description as well as how to
call the filter.

The image you sent before is a 2D image, and you should do some 2D skull
stripping (e.g. this
<https://www.researchgate.net/publication/264042031_Skull_Stripping_of_MRI_Using_Clustering_and_2D_Region_Growing_Method>
).

Also, can you try to keep the conversation on the mailing list so other
people can benefit from it in the future?

Hi D?enan Zuki?

Thank you for your reply.
I know that a 3D input produces a 3D output. I will try to explain better
my issue.
I have a 3D image and I want to get to a ROI (200x200x100 size) from that
image.
But the output image has to keep the original information, especially the
region size.
(400x400x550 in my case). The problem is that the output image is
200x200x100 size
and not 400x400x550 like the input image.

Thank you so much.
Oscar

Hi Oscar,

if you want to copy part of the image, and have the rest be filled with
zeroes, you should:

   1. create a new image
   2. copy information from the source image
   3. set regions using source's region
   4. allocate(true)
   5. use PasteImageFilter
   <https://itk.org/Doxygen/html/classitk_1_1PasteImageFilter.html> to copy
   a portion of source to the new image

Does this answer your question?

Regards,
D?enan

Hi all,



I noticed that the output of my registration is exactly as the moving
image, which means that the code below is not correct, but not sure where
is the mistake. I think it has to do with the transform initializer....



Thanks,

Hello Anton,

Yes, likely you are correct. Right now your code initializes using the identity transform and as far as I remember your B-spline grid doesn't physically overlap with your images (maybe it does, but this would be by chance).
What is a bit surprising is that you did not get an error with regard to too many samples outside the domain (indicating no overlap between images - so I am a bit puzzled as it means your images do overlap sufficiently).

This scenario is rare in practice and usually only happens when you are registering temporal data such as 3D volumes from a 4D CT dataset. Please see the following Jupyter Python notebook for an example on setting things up https://github.com/InsightSoftwareConsortium/SimpleITK-Notebooks/blob/master/65_Registration_FFD.ipynb . It will be easy for you to translate it to C#.


You will also likely need to initialize your registration by performing a registration using a global transformation (rigid/affine) and only then a local registration (FFD).

One last thing, there is a bug in the code in the line: R.SetMetricSamplingPercentage(30.0);

This is a 300% sampling. The expected values are in (0.0,1.0].


          hope this helps
                  Ziv

Subject: [ITK-users] Target Machine type error when trying to build 64-bit
	ITK using VS2015
Message-ID: <CAEhu9hDVDp4XY4uB9za_Vj14m8KJFfox4d61G-j1nnziP7R0KA@mail.gmail.com>

Hello all,

This may be more of a Visual Studio issue than an ITK issue, but I was
wondering if anyone else found a way around this.  I'm trying to build ITK
4.10.0 on a Windows 7 64-bit machine with Python (2.7 64-bit) wrapping
using Visual Studio 2015.  I should add I'm not familiar with either CMake,
ITK, or Visual Studio so I could be missing something obvious.

I keep getting the following error for multiple *.obj files:
x64\Release\*.obj : fatal error LNK1112: module machine type 'x64'
conflicts with target machine type 'X86'

I noticed that CMake generates vxproj files for only Win32 by default.
Then the files are modified by Visual Studio when switching the platform to
x64 and selecting "Clean Solution", which adds the following lines, among
others:
    <ProjectConfiguration Include="Release|x64">
      <Configuration>Release</Configuration>
      <Platform>x64</Platform>

However, many individual sub-projects are still not updated to account for
x64 configurations.  I took a look at the Advanced CMAKE variables in the
CMake GUI, but had no idea what to modify (everything seems to target
Win32).

Is there a way to configure CMake to generate x64 files?  If not, does
anyone know how to correctly configure ITK on x64 platforms in VS2015?

Thanks,
Evan Kao

Hi Evan,

you need to select "Visual Studio 14 2015 Win64" as the generator:
[image: Inline image 3]

The result of this should be that you only have x64 platform in Visual
Studio:
[image: Inline image 2]

Hi Matt and D?enan,

Thanks for your prompt replies. Would you please also add python wrapping supports for the three classes below? As a result, I can use B-spline registration under ITKv4 registration framework. Thanks in advance.

(1) itk::LBFGSBOptimizerv4
(2) itk::LBFGSOptimizerv4
(3) itk::TransformToDisplacementFieldFilter

Regards,

Zhuangming Shen

Subject: [ITK-users] streaming TileImageFilter for arbitrary number of inputs

Dear mailing list members,


Based on the examples for TileImageFilter I've created a working CLI to append 
an arbitrary number of inputs 
(https://github.com/romangrothausmann/ITK-CLIs/blob/4fdf5778022598dcf83fb38e6002df72bd67bef3/tile.cxx).
As there is an example that does not apply Update and DisconnectPipeline on the 
readers 
(https://itk.org/Doxygen/html/SphinxExamples_2src_2Filtering_2ImageGrid_2AppendTwo3DVolumes_2Code_8cxx-example.html#_a2) 

I changed my code such that a reader instance is created for each input in a 
for-loop:
https://github.com/romangrothausmann/ITK-CLIs/commit/ebfc0aea37d28cbbf2bb22c3f56be52453cebde9

However, the update from the writer seems not to propagate to the readers 
whether streaming or not. Can the TileImageFilter not stream in such a case or 
are further modifications necessary?

Thanks for any help or hints
Roman

Hello,

The TileImageFilter does not fully stream [1]. The filter also has some odd behavior, and other older implementation details. If you are going to work on a streaming pipelines it is best practice to examine the filters to determine how the Requested regions behave.

However, there is no reason that the TileImageFilter algorithm couldn?t support streaming. It is just a matter of code and a bunch of testing. A contribution for this issue would be welcomed! Also this filter is in need a refactoring and bring it up to several other best practices. There are several issue with the current implementation that would cause it not to work correctly with a streaming pipeline, and cause excessive execution.

You can also use the PipelieMoniotorImageFilter to record and print the pipeline interaction during Update [2]. This information helps with debugging and diagnosing problems, but if the pipeline is mis-behaving ( as the TileImageFilter may ), the information may not be correct.

I have tried similar streaming with the JoinSeriesImageFilter. However I ran into many problems with having hundreds of ImageIO being utilized at the same time. There were problems with having too many files open at the same time along with ImageIO libraries that couldn?t handle single threaded access to multiple files.

Many thanks Brad for Your detailed reply. I understand now the problems 
concerning streaming TileImageFilter.
However I still wonder why my non-streaming version also does not work any more 
after moving the creation of reader instances into the for-loop:
https://github.com/romangrothausmann/ITK-CLIs/blob/ebfc0aea37d28cbbf2bb22c3f56be52453cebde9/tile.cxx#L46-L50

Is this construct inappropriate for the TileImageFilter?
Why does it work for:

Hi,

Who is holding the pointer to the newly created ImageFileReader outside of the loop? For that type of operation I?ll frequently just stash smart pointers into a std::vector or list.

Regarding the example, look at the scope of the smart pointers with respect to the execution of the pipeline.

HTH,
Brad

Dear all,

I am submitting an insight journal paper, while uploading my example

like to upload a 89 MB zip file and attaching them one by one was the only
solution I could find so far.

I appreciate your help in advance,

Hello,
I am attempting to build the example in section 3.6.4 of the 2nd volume
Insight Toolkit user guide to read unsigned char data rather than float.  I
have narrowed the error I?m getting down to the
MeanSquaresImageToImageMetricv4, and the error I?m getting is:

error C2440: ?initializing?: cannot convert from
?itk::Concept::Detail::UniqueType_bool<false>? to
?itk::Concept::Detail::UniqueType_bool<true>?

I am using Visual Studio 2013 and ITK 4.10.0, any ideas on how to fix this
would be helpful. I read the Microsoft Compiler Error documentation but
didn?t really understand it.

Hi Andrew,

This itk::ConceptCheck [1] says that the pixel values must be float to
be used in itk::MeanSquaresImageToImageMetricv4 -- use an
itk::CastImageFilter to change the pixel type.

HTH,
Matt

Many thanks Brad for the hint of the smart pointer scope and storing it in 
std::vector, at least the non-SDI version now works as expected.

Hi Meikolin,

sp is a ImageType::SpacingType variable which is assigned on the line
before.

If you couldn't deduce that, you should really try going through ITK
software guide <https://itk.org/ItkSoftwareGuide.pdf>. Spacing is described
in chapter about data representation
<https://itk.org/ITKSoftwareGuide/html/Book1/ITKSoftwareGuide-Book1ch4.html>,
section "Defining Origin and Spacing".

Regards,
D?enan

Hello,
I am attempting to use the CastImageFilter to convert between unsigned char
and float image types, and am getting a System.AccessViolationException at
runtime.  I have seen reference to this being caused by referring to a
pointer that is out of scope, but in this case both the image and the cast
filter are delcared in the same method, so I?m not sure how it can be going
out of scope.  I can include the header and definition files if that would
be helpful.

Hello,

The most common mistake here would be forgetting to call Allocate on your image. Beyond that sharing your code would be helpful.

Message-ID: <DA2915A530468E47B3C4845298E6EB03833FB317@msgb06.nih.gov>


Hi!

We are pleased to announce the SimpleITK 0.10 Release Candidate 2 is now available! The release is expected to follow shortly.

There have been many improvements to better support wrapping for R. SimpleITK for R needs to be compiled from the source. 

The Python Java and CSharp binaries are available for download from Source Forge:

https://sourceforge.net/projects/simpleitk/files/SimpleITK/0.10rc2/


The latest versions of ?pip? is recommended to install the downloaded binary wheel for Python. Python eggs are no longer being distributed.

You are encouraged to checkout SimpleITK?s master branch in the git repository for testing building from the source code.

Also we have packages for the Anaconda Python distributions in the SimpleITK group and under the ?dev" label. These packages can be installed with the following command:

$ conda install -c https://conda.anaconda.org/simpleitk/label/dev SimpleITK

Since the 0.10rc1, there have been a number of configuration and fixes to support gcc 6.1. Additionally, new examples and updated documentation. Please see the git long for further information

Key Improvements since 0.9.1:
* The R language bindings have received extensive improvements and bug fixes.
* Added Image::SetMetaData method
* Added LandmarkBasedTransformInitializer
* Added MultiLableSTAPLEImageFilter
* Default sitk::Show support for Fiji over ImageJ
* Moved third-party packages Lua, gtest, virtualenv from source code to Superbuild projects
* Added Forbid Download option
* Enabled each language wrapping to be an independent project dependent on SimpleITK C++ interface and libraries.
* Lua languages bindings now compile as a loadable module
* Many CMake build improvements to default configurations
* CMake version 3.3 is now required

Enjoy!
Brad

That depends on you image. Try this

Thanks for getting back to me, after conferring with a colleague I tried
using the output of the cast filter directly in the subsequent pipeline
rather than writing it to a new image object of the filter's output type. I
got the same error doing that, and also got the same error just running
Update() on the cast filter, which leads me to believe I'm doing something
wrong in setting up the cast filter.  I'm attaching my code for the class
I'm writing, hope it's something simple I'm doing wrong. Currently it's
throwing the exception at line 85 when the registration transform
initializer is activated.

Hi Andrew,

I think that line 62 of .cpp should be:
castFilter->Update();
I don't see the pipeline updated elsewhere.

D?enan

Thanks D?enan, as I said in my previous email running Update() on the
castFilter pointer returns the same error.  I did put in a try/catch block
to update it though.

Subject: [ITK-users] In-place extraction of N-1 dimensional images from N
	dimensional images
Message-ID: <CAJbB22GozQHOk0U+6FTmXV05NL3XEg8ddN--RjkyVMYLu7BEDg@mail.gmail.com>

Hello,

I am working on an ITK/VTK viewer for visualizing 3D+time image data. The
data is represented by 4D images in ITK (x,y,z,t). I would like to be able
to access the 3D data in VTK without copying it, since that would slow down
scrolling through time in large datasets. I noticed that, although in-place
extraction should be possible, the ExtractImageFilter 'says no' to in-place
extraction when the input and output dimensions differ. Does anyone know a
way to achieve my goal using existing ITK functions? For example, if there
would be some way of reducing the dimension of 'flat' images, i.e. 3D
(Nx,Ny,1) to 2D (Nx, Ny), then I could still use the ExtractImageFilter.

Best,
Edwin

	image processing algorithms using Intel Threading Building Blocks
Message-ID: <20160728091318.B625A3D6205E@insight-journal.org>

Hello,

A new submission has been added to the Insight Journal.

Title: A new implementation of itk::ImageToImageFilter for efficient parallelization of image processing algorithms using Intel Threading Building Blocks
Authors: Jaberzadeh A., Scherrer B., Warfield S.
Abstract: Modern medical imaging makes use of high performance computing to accelerate image acquisition, image reconstruction, image visualization and image analysis. Software libraries that provide implementations of key medical imaging algorithms need to efficiently exploit modern CPU architectures. In particular, workstations with small numbers of cores are being replaced by very high core count architectures, and by many integrated core architectures, which offer acceleration by vectorization and multi-threading.

The Insight Toolkit (ITK) is the premier open source implementation of medical imaging algorithms, with a generic design for image processing filters that allows for many developers to rapidly incorporate these algorithms in to new applications.  While ITK filters benefit from a generic, platform independent multithreading capability,  the current implementation is difficult to exploit to achieve very high performance. Specifically, ITK relies on a static decomposition of the image into subsets of equal size which can be highly inefficient. Threads that terminate early due to uneven work throughout  the image finish early and do not contribute further to the processing of more complex regions, leading to idle computational resources and longer execution times. Performance is also difficult to coordinate across multiple algorithms, as the ITK filter assumes each filter operates independently but the global implementation has an impact across filters.  

In this work, we propose a novel, simple to use, high performance multithreading capability for ITK that accelerates the itk::ImageToImageFilter. We utilise a workpile data decomposition strategy, and leave the task of optimal job scheduling on CPU cores to the library called Threading Building Blocks (TBB). We demonstrate the efficacy of multi-threading with TBB in comparison to the itk::Multithreader class, through three simple example image analysis algorithms. 

Our implementation provides a new multi-threaded itk::ImageToImageFilter that can be conveniently reused to provide simple and efficient multi-threaded code across applications and algorithm libraries. Our new implementation is distributed as open-source software to the  community and is straightforward to adopt.

Have you tried calling Update on the import filter? That might be the
problem. Cast filter is simple and non-special, I doubt it is the problem.

Subject: [ITK-users] In-place extraction of N-1 dimensional images from

Hi Edwin,

you should be able to achieve your goal using import image filter
<http://www.vtk.org/doc/nightly/html/classvtkImageImport.html#details>. ITK
has import image filter too
<https://itk.org/Doxygen/html/classitk_1_1ImportImageFilter.html>, so you
can decide in which library to do dimensional reduction.

Regards,
D?enan

Hello,

I noticed you are using type int for you imageSiize. How big is your image? You may be overflowing when computing the number of pixels.

I don?t think you have provided a stack trace of when the error occurs. That would be helpful too.

I got the same error doing that, and also got the same error just running Update() on the cast filter, which leads me to believe I'm doing something wrong in setting up the cast filter.  I'm attaching my code for the class I'm writing, hope it's something simple I'm doing wrong. Currently it's throwing the exception at line 85 when the registration transform initializer is activated.

Thanks all for getting back to me.  I put in a call to update the
importFilter and upon debugging found that the image variable is getting
the correct size settings and number of elements (or at least it is the
same as the importFilter finds).  I tried casting the imageSize to unsigned
int and got the same numbers throughout, and still had the exception at
castImage->Update().  Here is the stack trace at the exception:

I'm attaching this as a txt file also because the formatting looks a little
weird in my email client, it might be easier to read as plain text.  One
other thing I forgot to mention, the window generated by the exception has
the following text as well:
Additional information: Attempted to read or write protected memory. This
is often an indication that other memory is corrupt.

Thanks again for the help.

I would focus on the input array now. The cast filter is perhaps accessing
elements past the end of the input array. Try passing a smaller number for
Z size and see whether that solves the crash (access violation).

Subject: [ITK-users] Insight journal dataset upload error
Message-ID: <CANWh7-AnDoDoBJVxD_Mt1w4qSUsLq+SX_WzfCqXx+JpbYFehbw@mail.gmail.com>

Dear all,

I am submitting an insight journal paper, while uploading my example
dataset, it is not possible to upload a file larger than 10 MB. I would
like to upload a 89 MB zip file and attaching them one by one was the only
solution I could find so far.

I appreciate your help in advance,
Amir

Thanks all for the help, I wrote a for loop to do the same task and got the
same error, and upon investigating it turns out the program I am building
upon was passing the incorrect dimensions for the image buffer. Turns out
this is a PEBKAC error.

Hi Toby,

Extract filter could theoretically run in place only when the extraction
region differs from largest possible region only along the slowest changing
index. To make this possible, ExtractImageFilter should
override CanRunInPlace() which it inherits from InPlaceImageFilter and
implement this theoretical check. Of course, other changes will be required
to make it function properly.

Regards,
D?enan

Hello,

I think the missing features to implement this proper is one step lower that the ExtractImageFilter, rather in the ImportImageContainer. The container would need to support presenting one buffer, but holding the whole buffer someplace. Also the ability to share buffers between images is not supported either. When filters are run ?InPlace? the output steals the buffer from the input, so there is no buffer sharing. This is essentially adding different ?view? to a buffer.

I had been concerned about the performance of the ExtractImageFilter filter previously. If I recall correctly I update the filter to use the ImageAlgorithm::Copy method and improved the performance by something like 100x for some test cases. You could profile the filter run with the default number of thread and with just 1 thread to determine how best to run it. Also you would need to veriify that the pipeline is executing as expected and efficiently. If this still does not meet your timing requirements you?d likely be better off just writing a function to create a ImportImageContainer with your ?view?, and manage the memory yourself. This would bypass the pipeline.

HTH,
Brad

Thanks for the technical details Brad.

I am going to plead lack of time (and understanding of ITK internals) here, and keep my code as-is. Maybe for the future some time.

Best wishes,

Hi JP,

The ITK Python import time was increased by a factor of two in 4.10.0
compared to 4.9.0 by hiding symbols in the generated libraries. The
next release of ITK will improve the import time by a factor of ten in
some cases because the lazy loading has been fixed [1]. Instructions
to try out the development version can be found here [2].

HTH,
Matt
