Speaker: Li Qi Title: Linked epipolar geometry for teleconferencing Abstract: In a teleconference, reprojecting a face can make it appear to be looking in a particular direction. Thus reprojection can substitute for an individual camera for each member of the conference, saving on hardware and transmission bandwidth. Our reprojection algorithm has an off-line part, which calculates fundamental matrices expressing the relationships of different points of view. During operation, the on-line part converts a single image into possibly several others that give conference participants the consistent impression that the speaker is addressing a particular person. Our offline algorithm presents only an easy version of the generally difficult correspondence problem. The demo in web page: http://www.cs.rochester.edu/~liqi/teleConferencing/teleConferencing.html shows how our algorithm is applied to a teleconferecing system.
