| Abstract: | The application for multi-wavelet in image compression was studied. Firstly, the basic principle of multi- resolution analysis of multi-wavelet was introduced. Secondly, a multi-wavelet compression algorithm of image was proposed, and finally the compression experiment for Barbara was conducted. Theoretically and experimentally, it shows that the proposed algorithm can acquire high PSNR and good visual effect with high compression ratio. |
