| Abstract: | Proposed a hybrid coding method, a block segmentation based on fractal dimensions is used, and introduced a invariant image moment to confine searching ranges.Experiments show that the compression ratio is improved and coding time is rreduced markedly, while the quality of decoding image is maintained. |
