摘　　要：文中研究设计了一种基于Altera公司的低成本EP4CE6E22C8N型FPGA的快速中值滤波器,充分利用该FPGA丰富的硬件逻辑和存储资源,借助流水线操作的思想,滤波效率是基于PC软件处理的传统中值滤波算法的3000多倍,完全满足数字图像处理系统实时性要求。This paper designed a fast median filter based on Altera's low-cost FPGA EP4CE6E22C8 N type,made full use of the rich hardware logic and memory resources of the FPGA,with the thought of the pipeline operation. The filtering efficiency is 3000 times of the traditional median filtering algorithm which is based on PC software processing,the design fully meets the requirements of real-time digital image processing system.
