Detailed Description

template<class TPixel>
class otb::GreyLevelCooccurrenceIndexedList< TPixel >

This class holds a VectorType of CooccurrencePairType with each pair is a combination of pixel index and frequency.

GreyLevelCooccurrenceIndexedList instance is created for every neighborhood iteration over the given input image. This class keep an internal itk::Array as a lookup array with size as [nbbins x nbbins]. The lookup array stores position CooccurrencePairType in the VectorType. It ensures us that all elements in Vector are unique in terms of the index value in the pair. For any given pixel index, -1 value indicates zero existence of the index in the VectorType. This avoid searching all elements in VectorType for each pixel index added during neighborhood iterator. It is also used to decide whether to update the frequency of pair or to insert a new element in the vector.
