Testing SDec in a fully automatic mode
with blind synthetic 1.5 D data. Model 2 (a posteriori)

Movie composed with the P-Tau Input and SDec-outputs for the model 2:the input: blind data, no a priori information;The column on the left: theoretical impulse trace: normal incidence.
the 1st SDec output: no free-surface related multiples;
the 2nd SDec output: sea-floor related intrabed multiples are removed;
the 10th SDec output: all of intrabed multiples are removed.
