| 摘 要： | 中值滤波是一种应用广泛的滤波方法。该文提出了一种改进的中值滤波算法。该算法对中值滤波进行了两方面的改进,一方面基于选点的方法,不对所有的点进行滤波;另一方面在对中值滤波的窗口进行可变处理。与中值滤波相比,它具有更好的平滑噪声和边缘保持功能,而且能有效地滤除图像中的随机噪声。

| Abstract: | Medianfilter is a widely used and effective nonlinearfilter in image processing.An improved median filter algorithm is presented in this paper.One method based on selecting point will not filter all pixel in image and a method of varing windows being used are proposed to improve median filter algorithm.Compared with the median filtering,the proposed method is better performance for preserving edges and smoothing noise. |
