Detailed Description

template<class TSample>
class itk::Statistics::MembershipSample< TSample >

Container for storing the instance-identifiers of other sample with their associated class labels.

This class does not store any measurement data. In a sense, you can think it as an additional information to basic samples (such as Histogram, PointSetListSampleAdaptor, and ImageToListAdaptor). The additional information is a class label for a measurement vector. Obviously without such basic types of sample, this one is meaningless. You can call any basic methods that has been defined in the Sample class such as GetMeasurementVector and GetFrequency. You can query the class label for an instance using an instance-identifier. Another new and important method is the GetClassSample method. With a given class label, it returns a pointer to the Subsample object that has all the instance-identifiers of instances that belong to the class.

This class is templated over the type of the basic sample. To use all the method, you should first plug in a basic type sample using the SetSample method
