摘要
针对高清图像在中值滤波预处理过程中排序量多、速度慢的特点,提出适合邻域图像并行处理机的分块存储方法。在流水线结构下,1个时钟周期可以并行处理32个3×3邻域的中值滤波运算,实现了高速、实时的1 920×1 080灰度图像中值滤波器。
Aiming at the characteristics of median filter that high quantity sort and low speed in high definition pre-processing, this paper introduces block storage method in neighborhood image parallel procesor, and in pipeline structure , one clock cycle can parallelly run 32 times 3×3 median filter operation.The system can implement median filter with 1 920×1 080 size quickly and real-timely.
