Curvelet-domain preconditioned "wave-equation" depth-migration with sparseness and illumination constraints
A non-linear edge-preserving solution to the least-squares migration problem with sparseness & illumination constraints is proposed. The applied formalism explores Curvelets as basis functions. By virtue of their sparseness and locality, Curvelets not only reduce the dimensionality of the imagin...
