| Abstract: | Based on the new developed multi-scale geometric analysis(MGA),a new algorithm for embedded image compression based on directional information is proposed in the paper.This new algorithm give us sparse coding frame based on directional information by image analysis in nature,and the human visual system is taken into account sufficiently in the compression algorithm.The proposed method has the improved accuracy and coding performance in image details,and this new algorithm can achieve high compression rate. |
