Restoration Method of Printing Image Based on Constrained Noise Energy

Abstract:

The method of constrained least squares based on noise energy constraine has been stated, which was applied to process images motion blur of original manuscript on images processing of electronic publishing in pre-press. From the technique of constrained least squares and limited energy of additive noise, restoration effect of printing image is improved greatly by adopting regularization idea to overcome ill-posed problem, estimate regular parameter of self-adaption and use space iterative algorithm. The experimental results show that the method can well reproduce the important information of the original image, and the SNR of the reproduced image at peak and the subjective vision effect are significantly improved. It is feasible and effective.
