2013-03-13 07:30:16 -0600 | asked a question | OpenCV reliably detect finger tips in webcam video I am developing an application that tracks fingers on a desktop/laptop keyboard for touch typing exercises. For demo purposes, I am detecting skin by thresholding the HSV hue value, which is working fairly well, and gives me a good image to work with: From here, I am grabbing a contour that is fairly accurate (although sometimes it is segmented, not sure how to deal with that yet), I get a convex hull of this threshold which is as accurate as the contour allows, and then detect convexity defects to try and find fingers and edges. The problem I have is that I need to be able to identify at least the pinky, ring, middle, and index fingers (thumb doesn't matter so much), but my results often times only find one or two fingers on each hand. Here is my relevant code: Any ideas for improvements? |
