利用矩阵的奇异值分解压缩图像，先将图像分块，对各块中的每个对应象素内积得到相关矩阵A，然后对A进行奇异值分解，选择n（n<N）个较大的特征值对应的特征向量，利用该向量与各块图像内积来压缩和恢复图像-matrix of singular value decomposition image compression, image first block of the block of each pixel corresponding to be associated with the plot matrix A, and then A singular value decomposition, the choice of n (4; N) 000 eigenvalues larger the corresponding eigenvector, the use of the Vector with the block images within the plot to image compression and restoration
