| Abstract: | This paper discusses a basic method of compressing image data based on the wavelet transform.Based on the Dictionary Coding Algorithm and according to the characteristics of data processed by wavelet transform,we give the Fuzzy Dictionary Coding Algorithm.With this algorithm,we can combine both quantization and encoding in traditional image compression methods based on transform.We get better compression effect. |
