| Abstract: | The importance of data compression in image process was described,and that wavelet transform is an important way to do image compression.The wavelet transform having implemented image compression by means of dissolving and re-synthesizing pixel of image was stated hereby which was also compared with the traditional one,i.e DCT.The individual compressed ration and effect were analyzed respectively.At last the superiority of wavelet transform for the image compressing was also detailed. |

| Keywords: | wavelet transform image compression wavelet-based |
