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
.
