| 摘 要： | 在对极值中值滤波算法进行研究与分析的基础上,提出一种在高噪声环境下改进的极值型中值滤波算法,该算法在原有算法的基础上提出如下改进:去除窗口中的全部噪声点,只对由信号点组成的有序序列取中值,并以该值作为输出值.实验表明,该方法滤波效果比较理想.

| Abstract: | In this paper, the extremum median filtering algorithm in image processing is studied and analyzed. Then it puts forward an improved one. The algorithm improves makes the original one as the following: Remove all the noises in the window, get the median of the new sequence and put it out. The result shows that the new improved algorithm is superior to the original one. |
