一种噪声无关的图像复原算法研究
RESEARCH ON A NOISE-INDEPENDENT IMAGE RESTORATION ALGORITHM
摘要
Abstract
In order to solve the problem of manifest degradation in image quality while accessing to digital images,it is urgently need an image restoration technique to reconstruct the image.Under the condition of the point spread function is known,we get rid of the traditional progress of calculating the gain matrix relying on noise,through this and proceeding from restoring the gain matrix,we make the restored image more approaching the original image.The new method rectifies in recursion process the phenomenon of either larger or smaller in gain filtering so that the errors generated caused by lack of noise information are reduced.Moreover,the new algorithm has lower time complex than other iterative algorithms.Experimental result shows that the new method can effectively guarantee the quality of the restored image and raises the efficiency as well.关键词
