I am currently creating an opencv program that identifies a hand in an image and then gets the contour of the hand only, in order for us to get the center (x,y)m in pixels, of the hand.

The problem is that whenever the image or video includes an arm or a face, we can't split or separate the hand from the contours of the arm or the face. We are currently using an HSV flesh colored histogram to get the contours of the hand.

is there a way to separate them, i just need the hand. also if the picture includes only a hand and some part of the arm. How can we isolate the palm itself from the rest of the picture. all we need is a clear center of the palm.

thanks in advanced.
