| Abstract: | Fractal image coding is the compression ratio highest code technology which at present may achieve, but long coding time has hindered its development. This article firstly introduced fractal theory and the lifting wavelet transformation theory. A hybrid image coding based on lifting wavelet transformation and fast fractal is presented. The experimental results indicate that this algorithm improves the speed of image coding and the compression ratio enhances greatly. |
