| Abstract: | In the field of still color image coding,there is a widespread problem that the correlation among components is not fully explored. In this paper,emphasis is placed on the high structural self similarity among components of a color image and a fractal coding method based on 2 D DCT is promoted. In this method,after reducing the redundancy within each component by 2 D DCT,the redundancy among components is further reduced by fractal coding. Simulation results demonstrate a better performance of this method than that of the JPEG method. |
