Salt Pepper噪声以及使用median filter来减少噪声 文章首发于个人博客:https://xydida.com/2022/2/27/ComputerVision/salt-and-pepper-noise/,转载请联系作者。 处理图像时,我们用的图片往往都会有很多噪声。在黑暗中或是设备感光器受到影响,拍出来的图像就会有很多噪声,俗称“噪点”,Salt & Pepper就是其中一种。...
The experiment shows that this method can powerfully denoise salt-and-pepper noise with good edge-preserving. 实验结果证明,这种方法不但能有效地滤除椒盐噪声,而且能够很好地保持边缘。 cjig.cn 2. Prepared in this experiment, a median filtering process, and salt and pepper noise generated by the im...
Together with an undercolor-removal process (59) in which a high-resolution black-component input to the half-toning process is significantly less than the minimum of the values of the color components throughout most of their range, this arrangement minimizes the salt-and-pepper noise that can...

为了有效地去除数字图像中的椒盐噪声,提高图像质量,本文 在分析一些典型消除噪声方法的基础上,给出了一种新的椒盐噪声去除算法。首先,针对椒 盐噪声的特点,设计了一种基于动态窗口和邻域像素统计信息的噪声检测算法,有效地区分 了噪声点与非噪声,然后对检测出的噪声
