This is a video of my first version of fingertip detection. It's based on points in the convex hull and the orientation of the hand (see previous post). It's still a bit shaky, expecially around the thumb. And it does only work when the fingers are fully stretched out. But it looks promising:
In the second video the hull, palm and finger points are transfered onto the canvas window. Here it's more obvious that this version is not quite ready to use.
The next step will be to detect whether the hand is open or closed and only try to find the fingers and orientation if it's at least partly open. And then of course improve the finger detection (maybe even finger direction detection).
