Detailed Description

template<typename TSample, typename TRegion>
class itk::Statistics::RegionConstrainedSubsampler< TSample, TRegion >

This an abstract subsampler that constrains subsamples to be contained within a given image region.

This is an Abstract class that can not be instantiated. There are multiple subsamplers that derive from this class and provide specific implementations of subsampling strategies.

This class is templatized over both the Sample and the Region with an assumed consistency between the Region and the way the Sample is generated.

Use SetRegionConstraint(region) to provide the region constraint. All returned subsamples will be contained within this region. This assumes that the instance identifiers in the sample correspond to an offset computed with the provided region.
