图像实时处理系统日益发展，这无疑对FPGA的广泛应用提供了良好的平台。针对在某些领域传统的中值滤波算法无法快速有效的对采集到的图像进行处理，采用改进中值滤波利用FPGA运行速度快、内部程序并行运行等优点，设计出具有高实时性、高灵活性的图像预处理系统。通过中值滤波算法特点运用Verilog硬件描述语言进行代码编写，并在Quartus II、Modelsim进行实现仿真，最后与MATLAB中值滤波仿真图及多级中值滤波进行对比，得出利用FPGA处理改进中值滤波不但能够顺利对图像进行中值滤波，而且具有运算速度快、低能耗的特点。
圖像實時處理繫統日益髮展，這無疑對FPGA的廣汎應用提供瞭良好的平檯。針對在某些領域傳統的中值濾波算法無法快速有效的對採集到的圖像進行處理，採用改進中值濾波利用FPGA運行速度快、內部程序併行運行等優點，設計齣具有高實時性、高靈活性的圖像預處理繫統。通過中值濾波算法特點運用Verilog硬件描述語言進行代碼編寫，併在Quartus II、Modelsim進行實現倣真，最後與MATLAB中值濾波倣真圖及多級中值濾波進行對比，得齣利用FPGA處理改進中值濾波不但能夠順利對圖像進行中值濾波，而且具有運算速度快、低能耗的特點。

The development of image real-time processing system has brought a good platform of the widespread use of FPGA. Aiming at the problem that traditional median filter algorithm cannot process collected images quickly and efficiently, this paper adopts improved median filter and makes use of advantages, such as fast running speed, parallel running of inner program, to design an image preprocessing system with high real time ability and high flexibility. Using the features of median filter and Verilog hardware description language to code. And then realize simulation in Quartus II and Modelsim. At last, compared with MATLAB median filter simulation figure and multilevel median filter, it has shown that using FPGA to process and improve median filter can not only conduct median filter to images successfully, but also has the ability of fast operation speed and low energy consumption.
