Description: 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 Platform: |

Description: 一幅图像对应于一个由若干迭代函数组成的迭代函数系统，迭代
函数系统的所有参数就构成图像的 IFS 码。因此，这种编码方法对具有典型分形
结构的图像能够实现非常高的压缩比 。-An image corresponding to an iterated function systems composed by a number of iterative function, iterative
All parameters function of the system constitutes an image of IFS code. Therefore, this coding method has the typical fractal
Image structure can achieve very high compression ratio. Platform: |
