#include <itkRecursiveLineYvvGaussianImageFilter.h>
1D recursive Gaussian blur based on Young-Van Vliet's algorithm, implemented for CPU.
This CPU implementation is more efficient than the GPU implamentation for smaller images (e.g. 512 and smaller for quadcores at over 3GHz); use the benchmark tests to establish the size for which this implementation performs better for your particular hardware configuration.

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.
Reimplemented from itk::Object.

RecursiveLineYvvGaussianImageFilter needs all of the input only in the "Direction" dimension. Therefore we enlarge the output's RequestedRegion to this. Then the superclass's GenerateInputRequestedRegion method will copy the output region to the input.
Reimplemented from itk::ProcessObject.
|
protected |
Apply the Recursive Filter to an array of data. This method is called for each line of the volume. Parameter "scratch" is a scratch area used for internal computations that is the same size as the parameters "outs" and "data". The scratch area must be allocated outside of this routine (this avoids memory allocation and deallocation in the inner loop of the overall algorithm.

Get the direction in which the filter is to be applied.

Get the image splitter to split the image for multi-threading.
The Splitter object divides the image into regions for threading or streaming. The algorithms on how to split an images are separated into class so that they can be easily be reused. When deriving from this class to write a filter consideration to the algorithm used to divide the image should be made. If a change is desired this method should be overridden to return the appropriate object.

Set/Get the flag for normalizing the gaussian over scale space. When this flag is ON the filter will be normalized in such a way that larger sigmas will not result in the image fading away.
When the flag is OFF the normalization will conserve contant the integral of the image intensity.
For analyzing an image across Scale Space you want to enable this flag. It is disabled by default.

Set up the coefficients of the filter to approximate a specific kernel. Typically it can be used to approximate a Gaussian or one of its derivatives. Parameter is the spacing along the dimension to filter.

If an imaging filter can be implemented as a multithreaded algorithm, the filter will provide an implementation of ThreadedGenerateData(). This superclass will automatically split the output image into a number of pieces, spawn multiple threads, and call ThreadedGenerateData() in each thread. Prior to spawning threads, the BeforeThreadedGenerateData() method is called. After all the threads have completed, the AfterThreadedGenerateData() method is called. If an image processing filter cannot support threading, that filter should provide an implementation of the GenerateData() method instead of providing an implementation of ThreadedGenerateData(). If a filter provides a GenerateData() method as its implementation, then the filter is responsible for allocating the output data. If a filter provides a ThreadedGenerateData() method as its implementation, then the output memory will allocated automatically by this superclass. The ThreadedGenerateData() method should only produce the output specified by "outputThreadRegion" parameter. ThreadedGenerateData() cannot write to any other portion of the output image (as this is responsibility of a different thread).
