【Abstract】 On the condition of the missing pixel information of the observed image during the process of imaging,based on the analysis of the degradation principle and establishment of the math model as well as discrete expression,this paper incorporates optimization method into the process of blur image restoration and proposes the deconvolution methods of non-zero background motion blurred image based on conjugate gradient optimization iteration.The experiment indicates that the result restores well with the proposed algorithm and it is a kind of effective method to restore motion blurred images.更多还原
