Hi, I know how to detect hands with Haar or skin color, but I want to detect exact hand positions for ASL-American Sign Language for deaf people. http://www.lifeprint.com/asl101/fingerspelling/images/signlanguageabc02.jpg
For instance, Haar would detect both letter A and B as hand from my image, because...well that's what it does, it detects hands. But how can I make it detect the exact hand position and make a difference between A and B?
Any answer helps, thanks for your time.
