computer-Assisted Auto Coloring (CAAC) has great potential in terms of lowering production cost and saving time in eel animation production. This paper presents our approach in auto coloring the frames in a sequence in traditional eel animation. First our previous work on feature-based region matching is introduced. Then stable topology information is proposed as the major improvement. Subsequently, the processes of matching master frames and coloring the first frame of a scene are described, followed by the introduction of auto coloring for inbetweens. With the assistance of stable topology, the accuracy of matching is much improved.

In this paper, we propose a system generating free-viewpoint video using multiple cameras and a PC-cluster in real-time. Our system first reconstructing a shape model of objects by the visual cone intersection method, secondly transforming the shape model represented in terms of a voxel form into a triangular patch form, thirdly coloring vertexes of triangular patches, lastly displaying the shape-color model from the virtual viewpoint directed by a user. We describe details of our system and show some experimental results.
