  endrov.flow.EvOpGeneral
      endrov.flow.EvOpSlice1
          endrov.flowImageStats.EvOpEntropyRect

public class EvOpEntropyRect
extends EvOpSlice1

Moving entropy. Entropy is taken over an area of size (2pw+1)x(2ph+1). Entropy is defined as S=-sum_i P[i] log(i), where i is intensity Complexity O(w*h*pw*ph), could be made faster with a method similar to huangs median calculator
