Abstract: To remove impulsive noise from color images, a ultra-fast Vector Median Filtering(VMF) method is proposed. In order to lower the computation of traditional VMF, the output of VMF is replaced by the nearest vector from the mean point in filtering window. Simulation experimental result shows that the method has almost the same performance with other new filters while lowering computation requirement and reduce the process time.

摘要： 针对如何消除彩色图像中脉冲噪声的问题，提出一种快速矢量中值滤波方法。判断当前像素对等组的数量是否为噪声，若为噪声则计算邻域窗口内距均值最近的矢量替代原矢量中值滤波的输出。仿真实验结果表明，与其他方法相比，该方法能减少窗口内大量的矢量距离计算，在保持滤波效果的同时，降低处理时间。
