Image Restoration Based on Wiener Filtering

The improved algorithm of image restoration is proposed which based on the image restoration by Wiener filtering.First,the Wiener filtering method is used to obtain the initial estimate of the degraded image,then,using the initial value to reconstruct the improved Wiener filter.And filter the degraded image again.The experimental results show that the method has less calculation,the advantages of high precision,and strong anti-noise capability.And the image restoration results are improved significantly compared with the results obtained by using traditional Wiener filters.
