Do you know of any image processing libraries besides OpenCV that have good documentation? If I was determined, I could figure out how to use most well made libraries eventually, but I want to get this over with as quickly as possible so that I can move on to other things. I'm currently not interested in trying anything that isn't fairly mature and widely used. Another library I looked at briefly was CImg, but their documentation website doesn't even seem to work. -- You are receiving this mail because: You are watching all bug changes.
