研究了在Neumann边界条件假设下,一类具有对称点扩散函数的模糊图像复原问题,将此类问题转化为不适定的二维离散卷积问题,基于离散卷积算子的性质,提出了图像复原的TSVD算法.实验验证了算法的有效性.%In this paper, we propose TSVD algorithm for restoring images blurred by a symmetric PSF under reflecting boundary condition. We transform image restoration into deconvolution problem. Based on the property of the discrete convolution operator, we give TSVD algorithm for image restoration. Numerical experiments are given to illustrate the efficiency of the algorithm.
