| 摘 要： | 为实现图像在空间分割和频率操作的对称展开，树中的所有节点需要频率展开和空间分割，为此，发展了M可分频率展开方法，并将它与冗余的空间和频率树结合以实现图像的自适应分析与压缩，对比实验表明，图像的对称展开的编码质量比较像的非对称展开的编码质量好。

| Abstract: | In order to implement a symmetric expansion in segmentation and frequency operations for images, all nodes in the trees need both frequency expansion and segmentation. For this reason, M-partitionable frequency expansion is developed,and is combined with the redundant space and frequency tree to realize image adaptive analysis and compression. The comparison experiment shows that the coding quality of a symmetric expansion of images is better than that of an asymmetric expansion of images. |
