#include <itkImageRandomSamplerSparseMask.h>

Detailed Description

template<typename TInputImage>
class itk::ImageRandomSamplerSparseMask< TInputImage >

Samples randomly some voxels of an image.

This version takes into account that the mask may be very small. Also, it may be more efficient when very many different sample sets of the same input image are required, because it does some precomputation.
