Abstract: In this paper we express the TSVD solutions to the discretized 2-D problem in terms of Kronecker products,thus illustrating how to get over the ill-posed of the problem and how all computations with the large matrix can be avoided.Experience results show that the method has a great effect in image debluring.

Key words: block Toeplitz matrix, Kronecker product, 2-D TSVD, image debluring

摘要: 研究了二维截断奇异值分解(2-D TSVD)在大规模图像恢复中的应用,起到了正则化的作用,克服了问题固有的不适定性,同时也解决了由于存储有限带来的问题。实验结果表明,该方法恢复效果显著。
