Multi-model full-waveform inversion

Abstract

We propose a multi-model formulation of full-waveform inversion that is similar to image decomposition into a "cartoon" and "texture" used in image processing. Inversion problem is formulated as unconstrained multi-norm optimization that can be solved using conventional iterative solvers. We demonstrate the proposed model decomposition approach by recovering a blocky subsurface seismic model from noisy data in time-lapse and single-model full-waveform inversion problems.
