I need some explanation regarding the interpretation of the contents of pSrcEdge pointer argument to ippiDenoiseCAST filter. Should it point to an edge image? The documentation says "edge detection filtered image", but I am not able to understand if it should point to an image that has just been filtered to make edge extraction easy (like smoothed version etc) or the actual edges have to be calculated and passed to the function?
clarification sought re. DenoiseCast
