摘要 矢量中值滤波方法是在中值滤波的基础上发展而来的，它具有与中值滤波几乎相同的滤波特性，即1任何单调变化的信号都将完全得到保留;2任何窄于(L-M)/2的脉冲都将被压制(这里 L 为滤波器的滑动时窗长度，M 为输出时窗长度)。与中值滤波相比，矢量中值滤波的最大特点是:在每个时窗位置处滤波后的输出是 M 个数据元素，因而运算速度是中值滤波的 M 倍。另外，矢量中值滤波是一种多参数滤波，在实际应用中具有更大的滤波选择性。文中最后讨论了矢量中值滤波在零偏移距 VSP 资料处理中的应用和效果。
Abstract：Vector median filtering (VMF) is based on median filtering(MF);therefore,VMF has nearly the same properties as MF:(1) full preservation of monotonously varying signals and (2) suppression of the pulses that are shorter than (L-M)/2 samples,where L is moving window length and M the output window length, Compared with MF,VMF has a major advantage: VMF is M times as fast as MF because VMF outputs M elements in each window.Besides, VMF is multiparameter filtering and has more filtering options in practice,The paper finally describes both the application of VMF to zero-offset VSP data processing and the effect.
