itk::Statistics::Subsample< TSample > Class Template Reference

#include <itkSubsample.h>

Detailed Description

template<typename TSample>
class itk::Statistics::Subsample< TSample >

This class stores a subset of instance identifiers from another sample object. You can create a subsample out of another sample object or another subsample object. The class is useful when storing or extracting a portion of a sample object. Note that when the elements of a subsample are sorted, the instance identifiers of the subsample are sorted without changing the original source sample. Most Statistics algorithms (that derive from StatisticsAlgorithmBase accept Subsample objects as inputs).

Examples

Examples/Statistics/BayesianPluginClassifier.cxx, Examples/Statistics/SampleSorting.cxx, and Examples/Statistics/Subsample.cxx.
