Lift and Relax for PDE-constrained inverse problems in seismic imaging
Zhilong Fang, Laurent Demanet
We present Lift and Relax for Waveform Inversion (LRWI), an approach that mitigates the local minima issue in seismic full waveform inversion (FWI) via a combination of two convexi…

Time-domain sparsity promoting least-squares reverse time migration with source estimation
Mengmeng Yang, Zhilong Fang, Philipp Witte +1
Least-squares reverse time migration is well-known for its capability to generate artifact-free true-amplitude subsurface images through fitting observed data in the least-squares…
