Image Blocking Blind Restoration Method Based on the Triangle Meshes
Ruihua Lü · 2008
Aiming at the high boundary noise caused by blocking method for image restoration of space-variant blurs,as well as the large computation cost of conventional genetic algorithm for blind image restoration,an image blocking blind restoration method based on the triangle meshes is proposed.The image blocks are divided by the triangle meshes according to the image degradation.The micro population genetic algorithm and the conventional genetic algorithm are alternately used to estimate the image blocks and the parameters of their point spread functions.The boundaries of image blocks are also mended in the overlaps.Experiment results show that the presented method is much faster than the conventional blocking genetic algorithm,the parasitic ripples are obviously reduced,and the quality of the recovered image is enhanced visibly.
