脉冲噪声的自适应滤除方法

Adaptive Removal of Impulse Noise from Images

为了在滤除图像噪声的同时更好的保护图像的细节,文中提出了一种基于非线性自适应滤波结构的改进算法。用中心加权中值滤波算法代替原方法中的中值滤波算法以及中值滤波代替均值滤波作为最终滤波结果输出。这种算法与同类算法相比,具有更好的滤波性能并能更好的保护细节,其效果明显优于中值滤波算法。

In order to achieve a better impulse noise cancellation as well as preserving image details,the author proposed a new algorithm based on the structure of non-linear adaptive filter.The median filter was replaced with the center weighted median filter and the mean filter with the median filter.The results compared with other similar algorithms show that the proposed algorithm gives a better performance and besides,it can work properly and provide significant improvement over the conventional median filter.
