| 摘 要： | 中值滤波是最早提出的一种有效抑制椒盐噪声的滤波算法，但其最大的缺点是模糊了细节部分．提出了一种改进的中值滤波算法，根据待测点与相邻像素点之间灰度值的相似性来区分噪声点与图像点，对噪声点应用中值滤波，而对图像点保留其灰度值不变，该算法在有效抑制椒盐噪声的同时能很好地保护细节．

| Abstract: | Median filtering is the earliest algorithm for effectively removing salt and pepper noise , but the greatest disadvantage of it is that it makes the details fuzzy . In this paper , an improved median filter algorithm is presented . It distinguishes the noise - points and the image - points based on the similitude between the gray - value of center - point and its neighborhood , and then the median filter is applied to the noise - points, and remains the gray - value of image - points . This algorithm can not only effectively removing salt and pepper noise ,but also protect the details. |
