Class ConvolveImageBox

java.lang.Object

boofcv.alg.filter.convolve.ConvolveImageBox

public class ConvolveImageBox
extends Object

Convolves a kernel which is composed entirely of 1's across an image. This special kernel can be highly optimized and has a computational complexity independent of the kernel size.
