WebPOCS interpolation is a simple and effective way to produce multi-dimensional interpolations that can de-alias seismic data well (Abma, 2009). While POCS should have at least half the traces live on the input, the POCS interpolation tends to be fairly robust in places where MWNI is difficult to parameterize. MWNI WebPOCS Interpolation. The POCS (projection onto convex sets) based interpolation method (Adorf 1993) is a conceptually simple, iterative scheme, directly applicable to regularly sampled observations with missing data, where the underlying continuous signal has a known (or assumed) fundamental period. The POCS method attempts to fill the data gaps …
