A pseudo running-median filter without the lag

A typical median filter, like an FIR filter, has a group delay of 1/2 the window length, which introduces a constant time lag. This pseudo-median filter instead maintains a window of sorted values, ...

Deblending of simultaneous source data using a structure-oriented space-varying median filter

Abstract: In seismic data processing, the median filter is usually applied along the structural direction of seismic data in order to attenuate erratic or spike-like noise. The performance of a ...
