基于分形吸引子与尺度无关的特点，提出了基于分形插值的图像编码方法。该方法对原始图像的亚取样图像进行分形编码，并将编码结果作为原始图像的近似分形码，在图像重建时，对原始图像的近似分形码进行分形插值解码，得到原始图像的逼近。实验结果表明，在压缩比和恢复图像质量受损不大的情况下，编码速度可提高近６倍。
Based on the feature that the fractal attractor has no relation with the scale, an image coding method based on fractal interpolation is proposed. In this method, the subsampled image of the original image is fractal-coded, and the result is used as the approximate fractal code of the original image. At the time of image reconstruction, the approximate fractal code of the original image is fractal-interpolated to obtain the approximation of the original image. Experimental results show that the coding speed can be increased nearly 6 times when the compression ratio and the quality of the recovered image are not impaired.
