数字图像中值滤波改进算法研究

Improvement of Medium Filtering on Digital Image

对传统的中值滤波算法进行了改进 ,新的算法采用同步更新迭代的思想 ,保持了传统算法的优点 ,同时取得到了更好的去噪效果 .实验证明 ,该算法不仅比传统的中值滤波算法降低了时间复杂度 ,提高了运算速度 ,而且去噪效果有了明显的改善 .

This paper modifies the traditional medium filtering algorithm,and provides a new algorithm which keeps the advantages of traditional algorithm and gets better results of dispel image noise by using iterative idea of synchronization renovating .The experiments testified that new algorithm not only reduces time of computing,but also gets obvious better results than those obtained by the traditional medium filtering algorithm.
