Integration of skin, edge, and texture to extract natural gesture

In this paper, we present a natural gesture extracting method integrating arm edges detection, skin color model and cloth texture feature. We use skin extraction result to guide arm edge locating and use arm edge information to verify skin extraction result. Thus, some small skin regions in background are discarded. Our method can cope with some special cases such as two hands placed together, and also distinguish left and right hands. Further more, we add texture feature of cloth into arm position evaluation. Now the requirement for corsetry or marks is no longer needed.
