Iterative Edge-Preserving Adaptive Wiener Filter for Image Restoration
Chikako Abe, Tetsuya Shimamura (Saitama Univ.) SIP2009-60 IE2009-85
Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, an image restoration method for noisy image corrupted by additive white noise is proposed. It is well known that the Adaptive Wiener Filter(AWF) is suitable for such restoration. However, some noises remain in an image restored by the AWF. In order to improve the performance of the AWF, an iterative algorithm is proposed. To prevent original image signal loss, a weighting parameter is used for the noise. Then, the filter applied to the edge region is adjusted using a modified filter kernel. Compared to the conventional AWF, the proposed filter provides better edge preservation.
