DiffusionInv: Prior-enhanced Bayesian Full Waveform Inversion using Diffusion models
Yuanyuan Li, Hao Zhang, Zhuoqi Yan +1
Full waveform inversion (FWI) is an advanced seismic inversion technique for quantitatively estimating subsurface properties. However, with FWI, it is hard to converge to a geologi…
