itk::ErodeMaskImageFilter< TImage > Class Template Reference

#include <itkErodeMaskImageFilter.h>

Detailed Description

template<class TImage>
class itk::ErodeMaskImageFilter< TImage >

This filter computes the Erosion of a mask image. It makes only sense for masks used in a multiresolution registration procedure.

The input to this filter is a scalar-valued itk::Image of arbitrary dimension. The output is a scalar-valued itk::Image, of the same type as the input image. This restriction is not really necessary, but easier for coding.

If IsMovingMask == false:
If more resolution levels are used, the image is subsampled. Before subsampling the image is smoothed with a Gaussian filter, with variance (schedule/2)^2. The 'schedule' depends on the resolution level. The 'radius' of the convolution filter is roughly twice the standard deviation. Thus, the parts in the edge with size 'radius' are influenced by the background.
--> radius = static_cast<unsigned long>( schedule + 1 );

If IsMovingMask == true:
Same story as before. Now the size the of the eroding element is doubled. This is because the gradient of the moving image is used for calculating the derivative of the metric.
--> radius = static_cast<unsigned long>( 2 * schedule + 1 );

virtual void itk::ErodeMaskImageFilter< TImage >::SetIsMovingMask ( bool  _arg )

virtual

Set the resolution level of the registration. Default: 0.
