Using bincodes to represent binary images is a storage-saving encoding sche
me. Region filling is a classical and important operation in the fields of
computer graphics. Given a contour, i.e., region boundary, represented by p
bincodes with their corresponding neighbor information, this paper present
s an O(p x d)-time algorithm for region filling, where d denotes the depth
of the corresponding bintree of the given bincodes. Experimental results ar
e illustrated to justify the performance of the proposed algorithm. (C) 200
