摘要

A seismic cube is determined, estimating the intersection of at least two seismic cubes corresponding to the different values of delay and/or angle of incidence. The estimate of the intersection is subtracted from one of the initial cubes. The differential cube obtained is treated by filtration. In addition the sum or difference of the filtered differential cubes is taken to estimate the difference between the two initial cubes.
