| Abstract | ||
| In this paper, a method is proposed to increase the compression ratio for the color images by dividing the image into non-overlapping blocks and applying different compression ratio for these blocks depending on the importance information of the block. In the region that contain important information the compression ratio is reduced to prevent loss of the information, while in the smoothness region which has not important information, high compression ratio is used .The proposed method shows better results when compared with classical methods(wavelet and DCT). | ||
