Abstract:
We describe our preliminary research on integrating MRI video with a 3D surface scan of a face. Our approach first extracts contours of a video by using snakes [KWT87, LL93]; then the outline structure of the video is matched with a close matching contour on the 3D face structure. The matching and alignment of the two representations uses curvature representations along with some simple heuristics about the relative locations of the facial features, such as nose and chin.
