Abstract
Summary In this work, we adopt the framework named Regularization by Denoising (RED) to solve the full waveform inversion problem in high-contrast media. The regularization by denoising technique only requires an image denoising engine, which, in our case, is a modified weighted total variation filter. One advantage of adopting the Regularization by Denoising algorithm for solving FWI problems is its simplicity in numerical implementation and selection of trade-off parameters. We have benchmarked our algorithm via the 3D SEG/EAGE overthrust P-wave velocity model. We also compare the proposed RED method with traditional FWI with Total Variation regularization.
