Can someone clear the way to calculate NPCR and UACI as some suggests to change one or more bits of each pixel value in image while otther prefers to change single pixel value in whole image and also some do by a change of single bit in key, Which is the correct way to evaluate these values?Can someone clear the way to calculate NPCR and UACI as some suggests to change one or more bits of each pixel value in image while otther prefers to change single pixel value in whole image and also some do by a change of single bit in key, Which is the correct way to evaluate these values? Can someone clear the way to calculate NPCR and UACI as some suggests to change one or more bits of each pixel value in image while otther prefers to change single pixel value in whole image and also some do by a change of single bit in key, Which is the correct way to evaluate these values? image processing, npcr, uaci, matlab MATLAB Answers — New Questions
