this is actually outside of the scope of Qt.
You should use a graphics processing library (like OpenCV - i don't know if it offers such functionality) to do such stuff. Or you need to implement an appropriate algorithmn yourself which uses the Qt API to access the pixel data.This is by far a complicated topic.
