摘要

Abstract

As the regularization method is used to carry out the process of image restoration,the regu-larization parameter is often needed.There should be different regularization parameter for the different im-age.The least square method is used to recover the fuzzy image,and it is not required to adjust the regulari-zation parameter,and the recovery process is simplified.In this paper,the first-order original-dual method is used to solve constraint least squares problem of image recovery,and an improved algorithm is put forward which using the method of overall substitution calculation.The experimental results show that the primal dual algorithm for least squares model using iterative computation time is greatly saved,and the improved primal-dual algorithm in the noise free image restoration effect is better than that of the primal dual algo-rithm.
