f Wavefield Interpolation - Continuation or Prediction Filter Techniques?

Irregular and sparse sampling of the wavefield in 3-D surveys generates spabal aliasing. Wavefield interpolation yields densely sampled data either operating in a suitable domain where sampling is more regular and can then be densified (e.g., in common shot domain) or by exploiting the predictability of the wavefield as parameterized by one (or more) plane events.
