Computer-Assisted Auto Coloring (CAAC) has great po tential in terms of lowering production cost and saving time in cel animation production. This paper presents our ap proach in auto coloring the frames in a sequence in tradi tional cel animation. First our previous work on feature based region matching is introduced. Then stable topology information is proposed as the major improvement. Subse quently, the processes of matching master frames and col oring 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.
