cv::Matchtemplate could be a start. It slides a reference image over a image and compares them at each position. But it could be hard to get that in realtime (maybe after downscaling your desktop image or moving it to a GPU).
Next option would be feature based (Sift, Surf, ORB,...).
Do you have a perfect match? (e.g. are you looking for a specific icon?)
yes i want to compare specific small image what program would have to find on my dekstop, they would be changing all the time of course so my program to do futher calculations would have to know what image exactly is on the desktop at this given time
If i use this cv::Matchtemplate could i also make screenshots in specific region on my desktop or i would have to click print screen all the time and somehow import that one into my program really fast?
