Robust GPS-Vision Localization via Integrity-Driven Landmark Attention
Navigation, 2022 For robust GPS-vision navigation in urban areas, we propose an integrity-driven landmark attention (ILA) technique via stochastic reachability. Inspired by cognitive attention in humans, we perform convex optimization to select a subset of landmarks from
