| 摘 要： | 在靶场测试实验中，为了节约经费和节省时间，需要将大量的视频图像进行高速传输与存储，以方便事后处理。研究了数字视频图像传输中一种基于FPGA（FieldProgrammableGateArray）的数字图像去噪方法，设计了基于FPGA的图像滤波器，并利用Matlab进行仿真实验。得出基于均值操作的自适应中值滤波方法对受到混合噪声污染的图像信息具有更理想的滤波去噪效果。

| Abstract: | In shooting range dynamic test, in order to save money and time, it will need a lot of high-speed vid- eo image to be transmitted and stored for post-processing. An image denoising method based on FPGA in digital video image transmission system is studied, the FPGA （Field and the software simulation using Matlab is completed. At last ring method that has more ideal filtering de-noising effects for Programmable Gate Array） image filter is designed a conclusion is drawn, it is adaptive median filte- image information polluted by mix noise. |
