| 摘 要： | 针对经典维纳滤波器存在的不足,提出一种新的自适应维纳滤波器.该滤波器能够根据不同的图像特性在给定的多个模板之间自适应地选择模板，使得滤波效果更加理想；并且相对于传统的维纳滤波方法，可以较完整地保存图像的轮廓信息.试验结果表明，新的自适应维纳滤波方法在主观和客观性能方面比传统的维纳滤波方法均有较大的改善.

| 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. |
