Abstract

We propose a novel compression algorithm for cell animation images. Conventional software algorithms include Cinepak, MPEG-1, Indeo5, etc., but these are for natural images, not for cell animation images. At low bit-rates, these provide relatively very poor image quality. In the proposed method, for intra frame coding, octree-based color quantization, ADPCM, and Golomb-Rice code are used. And for inter frame coding, block-to-block difference information is classified and coded. Therefore computational complexity is relatively low. The proposed methods outperform MPEG-1, FLC, and Indeo 5
