hi there i am currently doing a hand authentication system with the use of matlab and am stuck on how to extract the features of the image of the hand, i have already performed the rgb2gray, weiner and edge detections and now i have used the matlab image processing toolbox to locate the values of pixels and certain points of the hand how do implement this as a sort of algorithm and which technique is more effective.

You haven't described an algorithm, just some preprocessing steps. Authenticating (whatever that means) a hand is not just locating the values of some pixels of course - that won't do anything useful. What you need is a gesture analysis algorithm that does the kind of authentication you need, whether it's finger or palm print analysis, sign language interpretation, some sort of security application, or whatever. Look here for various algorithms: http://iris.usc.edu/Vision-Notes/bibliography/contentspeople.html#Face%20Recognition,%20Detection,%20Tracking,%20Gesture%20Recognition,%20Fingerprints,%20Biometrics

I'm virtually certain you will find papers describing such algorithms in the link I gave you. It's been talked about here before. Search Answers for things like hand, gesture, sign language, fingers, etc.
