Seismic data interpolation beyond aliasing using regularized nonstationary autoregression |

A missing trace test is shown in Figure 4a and comes from decimated-trace interpolation result (Figure 2c) after removing 70% of randomly selected traces. The curved event makes it difficult to recover the missing traces. The interpolated result is shown in Figure 4b, which uses a regularized adaptive PEF with 4 (time) 2 (space) coefficients for each sample and a 50-sample (time) 10-sample (space) smoothing radius. In the interpolated result, it is visually difficult to distinguish the missing trace locations, which is an evidence of successful interpolation. The filter size along space direction needs to be small in order to generate enough regression equations.
