Dear All,
Please help me understand the following error with regard to the code below.
I see that 'size' is a member of itk::FixedArray. How can I get the label
region ?
Thank you,
Emma
Error: Error 1 error C2039: 'size' : is not a member of
'itk::FixedArray<TValueType,VLength>'
typedef itk::LabelGeometryImageFilter< UCharImageType, ImageType>
LabelGeometryType;
LabelGeometryType::Pointer labelGeometry = LabelGeometryType::New();
labelGeometry->SetInput( relabel_filter->GetOutput());
labelGeometry->Update();
for(int i=1; i<numObjs; ++i)
{
ImageType::RegionType region = labelGeometry->GetRegion(i); //Line
causing problems.
//Do something...
}

optimizer

Dear list,
as I have written to this list before, I have to solve a calibration
problem for my current project. The problem is about finding eight
parameters for a coordinate transformation from 2D ultrasound image
space into a 3D world coordinate system defined by a tracking device.
The tracking device provides information about spatial position and
orientation of tracked objects (like a steel rod or something similar).
To find the eight parameters (6 for translation and rotation, 2 for
scaling), I need to solve a numeric optimization problem. So far, I read
some examples that use Levenberg-Marquardt optimizer for registration
problems, so I know how to setup the optimizer in general. I guess to
solve my problem, I need to implement some kind of mapper to do the
transformation from 2D into 3D coordinates with the ability to connect
the optimizer to this mapper class. What base class could I use to do so?
Regards
Michael

As many of you may know, we are working on
a major new version of ITK:
This will be ITKv4.
The main goals for ITKv4 are:
(1) Revising,
(2) Accelerating,
(3) Simplifying and
(4) Improving DICOM support in ITK.
To that end we have drafted a Transition Plan to go
from ITK 3.20 to ITKv4. The current form of this plan
is available in the Wiki page:
http://www.itk.org/Wiki/ITK_Release_4/Migration_Plan
A schematic representation of th plan is available at:
http://www.itk.org/Wiki/File:ITKv4-TransitionPlanProposal.png
The intermediate Phases of the Transition Plan
have been sketched out in
http://www.itk.org/Wiki/ITK_Release_4/Migration_Plan/Phases
an equivalent document is available at:
http://www.itk.org/Wiki/images/5/5c/ITKv4-TransitionPlan-Draft.pdf
Please share with us your impression on how
the current transition plan may impact your use
of ITK.
---
At this point, we have executed:
* Release of ITK 3.20 : July 15th
We are now in the process of:
* Porting ITK from CVS to Git.
As we move to Git, a lot of effort is being invested
in preserving the CVS history.
We anticipate that ITK-Git will be settle by the end of July.
It is therefore a good moment for you to start learning Git. :-)
Resources are available at:
http://git-scm.com/documentation
We recommend that you start by watching this talk
that Linus Torvals gave at Google:
http://www.youtube.com/watch?v=4XpnKHJAok8
Then follow up with the official Git tutorial
http://www.kernel.org/pub/software/scm/git/docs/gittutorial.html
( but, please note that there are many other
resources available for learning Git )
--
We will appreciate any suggestions on how to
improve the Transition Plan, and how to minimize
the effort that users will have to invest for migrating
to ITKv4.
Thanks
Luis

Huge commendations for making this change! It is very exciting. It will make
doing development with and for ITK much easier.

Hi Luis,
I have a MRI brain volume, i wanna to do that:
1- Extract the Brain only from the volume.??
2- Segment Brain to Gray / White matter/ ?CFS.? (may be tumor in the future will
be considered)
3- Output this segmented volume to FEM (Ansys) .??
Could you please let me know the shortcut to do that
Regards,
Yasser

Hi Yasser,
Do you need something more detailed than Skull-removal ?
The first thing in MRI will be to evaluate whether
you need bias-field correction or not.
Please provide more details on what you are trying to achieve.
???? Thanks
?????????? Luis
