A 1-D time-varying median filter for seismic random, spike-like noise elimination |

The 2-D seismic record can be represented by the following data sequence:

1. Setting the center point at the trace and the sample, and choosing samples in the trace,

2. Sorting the samples from smaller to larger, and then

3. Picking the center value, after sequencing, as the output at the point on the trace and the sample.

Repetition of the process on all data achieves 1-D stationary median filtering of the seismic record. The 1-D stationary median filter can be expressed as .
