HSV.cpp – hands detection demonstration
This is a screenshot of demonstration hands detection using the code hsv.cpp. Comparing with the old version within black background and green contours lines, this version actually is based on that. Besides, two functions are added in this new version: using rectangle to locate the hands location, and using eslipe to illustrate the angle of hands motion.

Hi, why are you using BGR values in hsv_min & hsv_max??
CvScalar hsv_min = cvScalar(0, 30, 80, 0);
CvScalar hsv_max = cvScalar(20, 150, 255, 0);
moreover, whats the need to convert the image from BGR to HSV ?
no sure hsv format images have to be used, but using hsv image is relatively easier to identify color ranges. hope this helps.
plz sir refer to this link
