Paper presented at the 2008 SEG Annual Meeting, November 9–14, 2008
Paper Number: SEG-2008-1546
... Summary A new approach is presented for inverse modeling to reconstruct continuous features in space, such as channels, that exhibit sparseness in a complementary basis (e.g. a Fourier basis) using observations in spatial domain. Continuity in space is used to constrain the solution...
