Real-time facial motion analysis for virtual teleconferencing
David J. Machin · 2002
Image analysis for a virtual teleconferencing system is described. Eyes are tracked in real-time using multiresolution grey-scale correlation. Locating the eyes allows the positions of other facial features to be approximated. The head orientation is calculated by comparing the eye locations in the video images to the positions of the top and sides of the head. The direction and gesture parameters are transmitted to a three dimensional animated 'clone' in a virtual office or virtual conferencing room.
