- The algorithm completes the matching of the range and domain block by way of transforming the square to the disk, snd expands the encoding dictionary. 本算法采用了将方块转换为圆盘的方式来完成值域块与定义哉块的匹配,扩充了编码字典。
- Taking the Brownian dimension as their texture feature, image blocks were clustered and sorted, to control the number of domain blocks to be compared with each range block in coding. 以图像的布朗维数为纹理特征对编码中的图像块进行聚类和排序,实现了对每个值域块所需比较定义域块数目的精确控制。
