| Abstract: | In this paper, based on the character of regularization parameter in regularized image restoration, the adaptive correction of regularization parameter (ACRP) is proposed to our new iterative restoration algorithm in space domain.By the ACRP,regularized parameter can automatic correct to appropriate value whatever the initial condition is. According to the character of symmetrical and positive definite matrix, we calculate its inverse matrix approximately and then the regularized fast approximately inverse matrix image restoration in space domain is elicited. The new image restoration algorithm can distinctly shorten the time of restoration and availably induce the ringing artifacts around sharp intensity transitions. |
