In this paper, a new intra and an inter shape coding algorithms that are based on chain code are proposed. In the intra mode, each segment is encoded by specific codes, and the decoding result is lossless. Compared with MPEG-4, M4R, DCC and chain code, the compression ratio is improved. Experimental results show that our proposed inter shape coding algorithm obtains better performance than MPEG-4 in compression.
