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...
