Abstract:
Computer-Assisted Auto Coloring (CAAC) has great potential
in terms of lowering production cost and saving time
in cel animation production. In this paper, a novel approach
to automatically color the animation character of line drawings
based on region matching and master frames is proposed.
Firstly, some important attributes of a region such
as curve length, character points, area etc. are investigated.
Then, based on these attributes, a detailed process of region
matching is presented followed by the coloring process. The
results show that our approach can straightforwardly handle
most cases, hence the aim of saving time and labor is
realized.
