为了克服分形图像编码方法速度低的弱点，提出了根据图像模型研究相应算法的思想。基于ρ｜ｒ｜图像模型，导出了与之相应的近距自相似模型，提供了一种适合于该模型的分形图像编码方法。实验结果表明，这种方法大大提高了编码速度，而且能有效地压缩图像数据
In order to overcome the weakness of the fractal image coding method with low speed, the idea of studying the corresponding algorithm based on the image model is proposed. Based on the ρ | r | image model, a corresponding short-range self-similarity model is derived and a fractal image coding method suitable for the model is provided. Experimental results show that this method greatly improves the encoding speed, and can effectively compress the image data
