摘　　要：根据分形图像编码的特点，阐述和研究了分形图像的解码方法。根据分形图像编码的特点，提出选择值域块均值作为迭代解码的初始图像，实验表明，采用值域块均值作为初始图像可以加快解码速度,只需少数迭代就可重构图像，并且可以和其它方法相结合。Based on the property of fractal image coding algorithm this paper expounds and studies the fractal image decoding algorithm. According to the characteristic of fractal image decoding, the average of range blocks is selected as an initial image of iterative decoding. Experimental results show that the reconstructed image can be obtained by a few iterations using the decoding algorithm mentioned before combined with other methods.
