boofcv.alg.filter.derivative.impl.GradientSobel_UnrolledOuter

public class GradientSobel_UnrolledOuter
extends Object

This is a further improvement on GradientSobel_Outer where it reduces the number of times the array needs to be read from by saving past reads in a local variable. This required the loops to be partially unwound. In tests it runs about 25% faster than GradientSobel_Outer.
