Detect specific finger tip in convexhull

[Dilan Shaminda]

Hi, i was able to detect finger tips and valleys using cvConvexityDefects() and Convexhull functions...now i want to identify what finger tip is belongs to what finger...for an example i want to detect finger tip of the thumb and do something..Need some tips...Thanks in advance :) :)

I would venture that you need to identify the entire hand contour and get the individual fingers. I think you need to find the skeleton – I think is is called erosion. Take a look at OpenCV for contour function. Vaclav

hi,thnx for the rply..i used cvFindCountours() function to get the contours of the hand..i will try the skeleton one as you suggested..but i want to know how to use depth value of convexitydefects to identify fingers...Thank you
