public class SoUnsharpMaskingProcessing
extends SoImageVizEngine

SoUnsharpMaskingProcessing engine The SoUnsharpMaskingProcessing engine harpens edges on the elements without increasing noise.

For an introduction to image filters, see section Images Filters.

This engine is a very common filter that sharpens edges on the elements without increasing noise. It first applies a Gaussian filter to a copy of the original image and blends it with the original. Undesired effects are finally reduced by using a mask to only apply sharpening to desired regions, that is regions of the gradient image that are above a certain size threshold.
