摘要:
为了在滤除椒盐噪声的同时能很好地保持图像的边缘细节,提出了一种新颖的图像椒盐噪声非线性滤波算法。利用局部统计信息,先将图像像素点分为信号点和可能的噪声点两类。然后将可能的噪声点进一步细分为边缘点、噪声点和信号点:利用方向信息、均方差来判断是否为边缘点,利用自适应阈值的方法来判断是否为噪声点,并且对边缘点和噪声点采取不同的方法进行滤波。经过仿真实验并与其它滤波算法进行比较表明,文中的算法具有更好的效果

In order to achieve very good salt-and-pepper noise removal as well as preserving image edge details,a new nonlinear algorithm is proposed in this paper. Utilizing the statistical information in a local window of the image,each pixel is classified to be s
