#include <itkImageRandomSampler.h>

Detailed Description

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

Samples randomly some voxels of an image.

This image sampler randomly samples 'NumberOfSamples' voxels in the InputImageRegion. Voxels may be selected multiple times. If a mask is given, the sampler tries to find samples within the mask. If the mask is very sparse, this may take some time. In this case, consider using the ImageRandomSamplerSparseMask.
