How can we extract the features of hand in real time situations?

I need to extract the feature of hand gestures (like showing 1,2 and 3) in frond of an USB camera to detect which gesture was shown and to send a serial data corresponding to each gestures recognized.

Please help me in finding the code as soon as possible.

As you know, this is not trivial and not some little chunk of code that can be pasted here. In fact it's undoubtedly the subject of some Ph.D. dissertations, many of which have been published here: http://iris.usc.edu/Vision-Notes/bibliography/contentspeople.html#Face%20Recognition,%20Detection,%20Tracking,%20Gesture%20Recognition,%20Fingerprints,%20Biometrics. In particular, check out section 21.4 on gesture recognition.
