无损图像压缩技术，具有高冗余的块。

说明：减少行的列：

输入：8x8块

输出：行参考矢量（逻辑）8x1双向

列参考矢量（逻辑）的1x8

减少矩阵

行的列扩展：

输入：行参考向量，列参考矢量和减少矩阵

输出：8x8块

Descr iption: Row Column Reduction:

Input: 8x8 block

Output: Row reference vector(logical)8x1

　　Column reference vector(logical)1x8

　　Reduced matrix

Row Column Expansion:

Input: Row reference vector,column reference vector and reduced matrix

Output: 8x8 block
