Face images and hand gestures provide a very ef# fective means of visual communication between humans. Similarly automatic face and gesture rec# ognition systems could be employed for contactless human-machine interaction systems. How# ever, developing such system is difficult, because faces and hands are both complex and highly vari# able structures. We describe how flexible models can be used to represent appearance variations of faces and hands and how these models can be used for tracking and interpretation. Experimental re# sults are presented for face pose recovery, face identification, expression recognition and gesture interpretation. 1 Introduction This paper addresses the problem of locating and interpreting faces and hand gestures in images. By interpreting face images we mean recovering the 3D pose, identifying the individual and recognising the expression; for the hand images we mean re# cognising the configuration of the fingers. In both cases different instances of the ...
