title: How to compare a webcam image/video to a specific image/video?
body: <p>I am basically just starting out in computer programming; mostly fluent in basic Java. I have an idea of creating an ASL (American Sign Language) to English, and my initial problem is how to identify hand movement from a webcam then comparing them to Signs that is already stored as an image or another video.  If the problem is a bit too advanced for me then please list any major concepts that I can learn. Please and thank you.</p>
