Missing data interpolation by recursive filter preconditioning
Sergey B. Fomel, Robert G. Clapp, Jon F. Claerbout · 2000
Missing data interpolation problems can be conveniently preconditioned by recursive inverse filtering. A helix transform allows us to implement this idea in the multidimensional case. We show with examples that helix preconditioning can give a magnitude-order speedup in comparison with the older methods.
