The Improved Winner Filter Image Restoration Based on Partition

Image restoration is a key research field in the digital image processing technology. Due to camera defocus, the relative movement and noise, the image quality declines. Because of the limitations of Wiener filtering method, the paper proposes a kind of improved Wiener filtering restoration method based on the partition. The method can not only enhance the edges and eliminate the noise, but also eliminate pseudo morph well. The PSNR of improved restoration method is higher than the original method.
