Line segments are powerful features complementary to points. They offer structural cues,
robust to drastic viewpoint and illumination changes, and can be present even in texture …

In contrast to sparse keypoints, a handful of line segments can concisely encode the high-
level scene layout, as they often delineate the main structural elements. In addition to …

Compared to feature point detection and description, detecting and matching line segments
offer additional challenges. Yet, line features represent a promising complement to points for …

An image line segment is a fundamental low-level visual feature that delineates straight,
slender, and uninterrupted portions of objects and scenarios within images. Detection and …

Event cameras respond primarily to edges---formed by strong gradients---and are thus
particularly well-suited for line-based motion estimation. Recent work has shown that events …

Here, the challenges of sample efficiency and navigation performance in deep
reinforcement learning for visual navigation are focused and a deep imitation reinforcement …

Along with feature points for image matching, line features provide additional constraints to
solve visual geometric problems in robotics and computer vision (CV). Although recent …

Visual Simultaneous Localization and Map** (VSLAM), which serves as the primary
technique for locating autonomous vehicles, has gained tremendous development over the …

Abstract Three-dimensional (3D) lines are common elements in artificial scenes and serve
as basic, yet essential features for structural 3D reconstruction. The crucial step of 3D line …
