|Inverse B-spline interpolation|
Forward interpolation plays only a supplementary role in this paper, but it has many applications of its own in the seismic processing practice. It is sufficient to mention such applications as trace resampling, NMO, Kirchoff and Stolt migrations, log-stretch, radial transform, etc. Two simple examples appear at the end of this section.
The general form of a linear forward interpolation operator is
