ABSTRACT

                    Recently,  a  number  of  computer-
aided  paint systems have been developed to improve the
colour  painting process, traditionally one of the most
time-consuming  steps  in 2-D cel animation production.
However,  much  improvement  remains  to be made in the
design of these new systems.

                    In   this   talk,   we  describe  a
region-based   cel   painting  design  which  uses  the
"paint-by-number"  method  and  is  based  on a virtual
frame  buffer  model.  In this region-based design, the
regions are recognizable, defined entities. This allows
us   to   define   functions   for  conceptually-based,
interactive  painting  techniques,  which can be easily
implemented.   Furthermore,  the  availability  of this
additional    region    information    introduces   the
possibility  of  automatic multi-frame colour tracking,
which  can  be implemented by transforming this problem
into  a  well-known  maximum  matching problem in graph
theory.  Thus, this new region-based design builds upon
techniques  used  in  earlier systems and paves the way
for future improvements.
