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...
