随着现代科学技术的发展，图像处理技术取得了巨大进步，在舰船等交通领域得到广泛应用。由于舰船航行条件一般都比较复杂，拍摄出的图像不够清晰，所以需要利用图像处理技术对图像进行处理。本文针对目前舰船图像处理存在的问题，研究基于FPGA图像处理的算法，在现有冒泡算法和一般快速排序算法的基础上，提出一种适用于舰船图像处理的基于横向拓展的新快速滤波算法，并通过QUARTUS9软件和Matlab仿真实验验证。结果表明，新算法在执行速度和图像处理效果上都优于前2种算法，有效提高了FPGA处理图像数据的速度，可以方便地应用于舰船图像处理。

With the development of modern science and technology, image processing technology has achieved great progress, has been widely used in ships and other traffic areas. As the ship navigation conditions are generally very complex, the image shot out is not clear enough, so needs image processing by processing technology. Aiming at the problem of image processing on ships, we researched the image processing algorithm based on FPGA and proposed a new fast filtering algorithm by horizontal expansion the window based on the existing bubble algorithm and the general algorithm of quick sort on, we passed through the QUARTUS9 software and MATLAB simulation experiments. The results showed that the new algorithm is better than in the speed of execution and the effect of image processing on the first two kinds of algorithms and this algorithm can improve the processing speed of FPGA image data effectively, can be easily applied to the image processing on ships.
