基于FPGA图像处理快速统计排序滤波实现

Fast Algorithm for Order Statistic Filtering of Image Processing Based on FPGA

以FPGA为平台，提出了图像处理并行快速统计排序滤波算法。该算法首先采用全并行比较方式实现滤波窗内数据排序，然后通过流水线方式实现滤波输出。根据此算法可进行最大值滤波、中值滤波等统计排序滤波处理，提高了处理速度。经过仿真试验，与传统的统计排序滤波相比，该快速统计排序滤波算法的实时性好，可实现性强。

Here a fast order statistic filtering （FOSF） algorithm is proposed. The algorithm sorts the pixels in the filtering window with synehronous parallel, then gets data output of filtering with pipelining. The algorithm greatly improves the efficiency of implementing maximum filtering and median filtering. The experiment verifies that the algorithm is of high availability.
