Automatic face and gesture recognition (which encompasses image and video-based face recognition, facial expression recognition, and hand gesture and body movement analysis) is rapidly developing into a highly active field of research.  Areas of interest include contactless man-machine interfaces and interaction with virtual worlds, access control, automatic search in visual databases, analysis of face, gesture and gait movements, feature identification, 3-D data acquisition, and physics-based modeling.

Below are sites of interest in the field of face recognition.  Most of these sites are commercial and illustrate the practical applications of face recognition in industry today.
