All Implemented Interfaces:

ImageFilter

public class IntegralImageFilter
extends AbstractIntegralImageFilter

computes integral image. result is stored in the allocated image to be retrieved. Basically it is sum of all pixels from top-left part of image relative to current pixel. this filter can work in place, but intended usage tells us to create and cache destination image
