How to detect the pixels which colors have been modified ?
I load a picture using OpenCV. I display it and colorize with the mouse cursor a cerain area of it and save the resulted picture. Does OpenCV allow to get the list of pixels which colors have been modified ?
Yes simply find absolute difference of two images.http://docs.opencv.org/modules/core/doc/operations_on_arrays.html#abs
Thank you, but the return value of that function is void, it does not list the pixels that are different
what function? Add your code!
