提出快速排序统计滤波 (FOSF)算法 ,利用相邻滑窗的重叠性质 ,通过把灰度直方图改造为静态链表的形式 ,实现排序统计滤波。由于无须对滤波窗内的象素进行排序 ,所以大大提高了算法效率 ,并取得较好的实验效果。
A fast ranking statistical filter (FOSF) algorithm is proposed. By using the overlap property of adjacent sliding windows, the ranking histogram filter is realized by transforming the gray histogram into a statically linked list. Since there is no need to sort the pixels in the filtering window, the efficiency of the algorithm is greatly improved and a better experimental result is achieved.
