Detailed Description

a processor for non-maximal suppression For every pixel in an image, a parabola fit is applied along the gradient direction, and the maximum point on this parabola is used to get the sub-pixel location of the edge.

The pixel point must qualify for being a maximum, i.e. it should have higher values than the interpolated sub-pixels along the positive and negative gradient direction.

Below drawing shows the face numbers at a pixel and is for author's own reference.
