Paper Abstract

The paper reports on investigations concerning the application of block oriented fractal coding schemes for encoding of color images. Correlations between the different color planes can be exploited for the aim of data compression. For this purpose the similarities between the fractal transform parameters of one block location but different color planes are regarded in a blockwise manner. Starting-point is the fractal code for one block in the dominant color plane which serves as prediction for the code of the corresponding block in the other planes. Emerging from this prediction the depending codes can be derived by a successive refinement strategy. Since the fractal code for the dominant color plane and the refinement information for determining the code for the other planes can be represented with fewer bits compared to the independently calculated ones, a coding gain can be achieved.
