Multi-Dimensional Interpolation Techniques: POCS

POCS: Multi-Deimensional Projection Onto a Convex Set* (licensed from BP) is a high dimensional interpolation that exploits the FFT algorithm to improve the wide azimuth coverage and fold of your data prior to PSTM/PSDM.

• 3D wide azimuth Interpolation with special options for Land and Marine
• Based on the well known technique of Projecting Onto a Convex Set
• Data needs Regularization, described below
