Conditional Denoising Diffusion Probabilistic Model for Ground-roll Attenuation
Yuanyuan Li, Hao Zhang, Jianping Huang +1
Ground-roll attenuation is a challenging seismic processing task in land seismic survey. The ground-roll coherent noise with low frequency and high amplitude seriously contaminate…

Misfit function for full waveform inversion based on Earth Mover's Distance with dynamic formulation
Peng Yong, Wenyuan Liao, Jianping Huang +2
Conventional full waveform inversion (FWI) using least square distance (LSD) between the observed and predicted seismograms suffers from local minima. Recently, earth mover's dista…
