Research on restoration method of image degraded by two kinds of blur

If observed image degraded by two kinds of blur simultaneously,the degraded function of whole degradation process is difficult to ascertain.And the blind image restoration which usually applied on the problem has unconquerable limitation.So here propose a method that implementing layered restoration based on image interpolation and image analysis.The method improves the analysis ability of low resolution image through image interpolation.After analyzing and pretreating image,choose the perfect parameters combination of the two degradation functions mutually under the optimization rule.With the two degradation functions known,the layered restoration can be implemented.The satisfying image restoration results are gained by means of computer simulation.
