Class PixelPairFeatureAnalyzer

java.lang.Object
  analysis.PixelPairFeatureAnalyzer

public class PixelPairFeatureAnalyzer
extends java.lang.Object

This feature analyzer assumes that the pairs exist in some sort of spatial structure, with the notion of horizontally and vertically adjacent pairs. Thus, specification of that structure's width and height is required.
