Image-Domain Least-Squares Migration via a Deep Feature Deconvolution Network

Least-squares migration (LSM) improves seismic imaging resolution by compensating for Hessian-induced blurring, but the explicit construction and inversion of the full Hessian remain computationally prohibitive. Image-domain LSM (ID-LSM) commonly uses point-spread functions (PSFs) as local representations of the Hessia...

Half-Quadratic Splitting with Learned Regularization for Image-Domain Least-Squares Migration of Marine Seismic Data

Marine seismic imaging is affected by limited acquisition aperture, nonuniform illumination, and complex features such as seafloor structures and low-velocity gas clouds. These factors can produce blurred reflectors, amplitude imbalance, and migration artifacts in conventional reverse-time migration (RTM). Point-spread...
