摘　　要：为改进图像中值滤波传统算法占用资源量大,计算耗时多的不足,在分析了基于现场可编程门阵列(FPGA)的传统图像处理技术基础上,提出改进算法,通过直接找出像素值中的最大值、中间值和最小值的方法,快速找出中值,达到减少逻辑资源的占用和计算量,缩短图像处理时间的效果。实验结果表明,该方法能有效抑制图像噪声,改善图像质量,提高图像处理速度。In order to improve the shortage of traditional algorithm on image median filtering, such as large resource occupancy, and much time cost of computing, an improved algorithm is put forward after analyzing the traditional image processing technology of field-programmable gate array （FPGA）. The me- dian value is gotten quickly by finding out the maximum, median, minimum of pixel value. The purpose of reducing logical resource occupancy, computing and image processing time is achieved. The results of test show that the method can restrain noise improve quality and increase speed of image processing effec- tively.
