#include <itkZeroCrossingImageFilter.h>
This filter finds the closest pixel to the zero-crossings (sign changes) in a signed itk::Image.
Pixels closest to zero-crossings are labeled with a foreground value. All other pixels are marked with a background value. The algorithm works by detecting differences in sign among neighbors using city-block style connectivity (4-neighbors in 2d, 6-neighbors in 3d, etc.).

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.

ZeroCrossingImageFilter needs a larger input requested region than the output requested region (larger by the kernel size to do comparisons between the central pixel and ite neighbors). Thus ZeroCrossingImageFilter needs to provide an implementation for GenerateInputRequestedRegion() in order to inform the pipeline execution model.

ZeroCrossingImageFilter can be implemented as a multithreaded filter. Therefore,this implementation provides a ThreadedGenerateData() routine which is called for each processing thread. The output image data is allocated automatically by the superclass prior to calling ThreadedGenerateData(). ThreadedGenerateData can only write to the portion of the output image specified by the parameter "outputRegionForThread"
