说明：  分形图像编码是一个相对较新的图像压缩技术。在分形图像编码中，通过利 用自然图像中存在的不同子图像间的跨尺度相似性（即把图像视为分形） ，一幅图 像用一个使图像近似不变的压缩仿射变换 的参数来表达，压缩文件中储存的是这 些参数的量化值而不是图像本身的象素值
(Fractal image coding is a relatively new image compression technology. In fractal image coding, by Lee Similarity with the cross-scale natural images exist between different sub-images (ie, images deemed fractal), a picture Like using a compressed image to approximate the same affine transformation parameters to express, compressed files are stored in this Quantization values of these parameters instead of the image pixel values themselves)
