摘要:
为了在各种噪声密度条件下，都能恢复椒盐噪声污染的图像并能很好地保持图像的细节，提出了一种基于改进的非对称裁剪中值滤波算法清除椒盐噪声。该方法首先对噪声点进行检测，然后基于滑动窗口中噪声点的数目来自适应改变窗口的大小，最后应用一种改进的非对称裁剪中值滤波器计算中值，结果显示该算法各项指标都要优于其它算法。实验结果表明了在各种的噪声密度条件下，该算法能较好地清除椒盐噪声，而且也能较好地保护图像细节，比现存的一些中值滤波算法清除椒盐噪声的效果更加优秀
Abstract:
In order to restore the image as well as preserve image details with salt-pepper noise under a wide range of noise densities, pro- pose a median filter algorithm based on improved unsymmetrical trimmed for removal of salt-pepper. This way firstly check the salt-pepper noise,then according to the number of noises in the window adaptively adjust the filter window size, finally get median by an improved unsymmetrical trimmed median filter. The results show that this algorithm is better than other algorithms in each index. The experimental results show that this algorithm may better eliminate salt-pepper noise and effectively protect image detail well, and it has a outstanding result for removal salt-pepper in comparison with other existing median algorithms under all kinds of noise densities
