DeepLSD: Line Segment Detection and Refinement with Deep Image Gradients DeepLSD is a generic line detector that combines the robustness of deep learning with the accuracy of handcrafted detectors. It can be used to extract generic line segments from images in-the-wild, and is suitable for any task requiring high precision, such as homography estimation, visual localization, and 3D reconstruction. By predicting a line distance and angle fields, it can furthermore refine any existing line segments through an optimization Paper: https://arxiv.org/abs/2212.07766v1 Github: https://github.com/cvg/deeplsd Dataset: https://paperswithcode.com/dataset/hpatches @computer_science_and_programming
