Sparsity constraints using a Laplacian kernel to get geological structures from potential field data

ABSTRACT We propose a new method for including sparsity constraints into potential field data inversion using a Laplacian kernel. The method obtains three‐dimensional density distributions, which are at best a proxy for geological structures. Compressive sensing has been used in many domains to reco...
