Abstract: Aimed at improving the insufficient result of classic Wiener filtering, a new adaptive Wiener filter is proposed. The new filter can adaptively select the filter template from different given templates, giving a better filtering result. The traditional Wiener filter seeks to suppress noise in images at the cost of losing some edge information, while the proposed method can overcome the problems. Experimental results show that the proposed filter gives improved performance both in subjective and objective evaluations as compared to the classic Wiener filtering.
