Detailed Description

template<class TPrecision>
class otb::VirtualDimensionality< TPrecision >

Estimates the number of endmembers in a hyperspectral image with the Virtual Dimensionality (HFC) method.

This filter applies the HFC-VD (Virtual Dimensionality) algorithm to an hyperspectral image and outputs the number of endmembers. It takes as input the covariance and correlation matrices of the input data, the number of observed pixel for thoses matrices estimations, and outputs the number of endmembers, and the log-likelihood.
