Robust Hand Detection via Computer Vision

Question

I am currently working on a system for robust hand detection.

The first step is to take a photo of the hand (in HSV color space) with the hand placed in a small rect

Answer 1

Here is a paper on adaptive gaussian mixture model skin detection that you might find interesting.

Also, I remember reading a paper (unfortunately I can't seem to track it down) that used a very clever technique, but it required that you have the face in the field of view. The basic idea was detect the person's face, and use the skin patch detected from the face to identify the skin color automatically. Then, use a gaussian mixture model to isolate the skin pixels robustly.

Finally, Google Scholar may be a big help in searching for state of the art in skin detection. It's heavily researched in adademia right now as well as used in industry (e.g., Google Images and Facebook upload picture policies).
