【Abstract】 There are several different parts of data in quad-tree fractal image compression. Each part is different in the sensitivity to the communication channel noise. In this paper, the different sensitivities of each part of fractal image compression data to the communication channel noise were first analyzed. Based on this, a combined source-channel coding of fractal image compression was proposed. Distortion of the proposed coding scheme was analyzed and an optimal algorithm was used to minimize the total distortion.更多还原
