| 摘 要： | 本文介绍一种均值加速中值滤波迭代算法,该算法不需要对所有像素的邻域值进行排序,而是对像素的邻域值有选择性的排序,排序后的中值直接替代原像素值。理论分析与实验结果表明:该算法能有效地降低中值滤波算法的时间复杂度,可将常用的快速排序算法复杂度(ONlnN)简化为O(N(1 lnN)/2),且去噪声效果良好,在图像处理中有广泛的应用前景。

| Abstract: | This paper introduces a fast algorithm of medium filtering.The algorithm chooses some elements for sorting order not all elements by using the means of value.And the position of new median is not for a new array,but instead of original value.The theory analysis and the experiment results show that the fast algorithm has reduced the time complexity of coding and sorting order algorithm from O(NlnN) to(N(1 lnN)/2).The results also show that the algorithm can well get rid of the noise,and there is a widespread foreground in digital image processing. |
