Adnan - did you check the link I gave you below??? It's a list of virtually all image processing articles on the subject. Also have you checked the File Exchange for lips and related things like face recognition?

They're the oval shaped thing in the lower middle of the face. Seriously, why don't you look up one of the ways people use to find lips here: http://iris.usc.edu/Vision-Notes/bibliography/contentspeople.html#Face%20Recognition,%20Detection,%20Tracking,%20Gesture%20Recognition,%20Fingerprints,%20Biometrics
