Using OpenCV to detect a finger tip instead of a face

Question

I'm using the facedetect example and going from there. Right now it only detects faces. Could someone point me in the direction to detect finger tips. Thanks

Answer 1

You could use cvFindContours and then check each contour to see if it could be a finger tip and go from there.

It might be easier if you do some pre-processing of the image so that the finger tips stand out, for example mask out colors that don't match the fingers.

Answer 2

Put a simple bright fluorescent sticker on the finger tip with a black dot in center or something like that. or even fashion a finger cap with a pattern printed on it which can be easily differentiated by the camera and your problem is very much solved.
