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 …

Line segments are ubiquitous in our human-made world and are increasingly used in vision
tasks. They are complementary to feature points thanks to their spatial extent and the …

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 …

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

Real-world objects and environments are predominantly composed of edge features
including straight lines and curves. Such edges are crucial elements for various applications …

We propose an approach for estimating the relative pose between calibrated image pairs by
jointly exploiting points, lines, and their coincidences in a hybrid manner. We investigate all …

We introduce LDL, a fast and robust algorithm that localizes a panorama to a 3D map using
line segments. LDL focuses on the sparse structural information of lines in the scene, which …

We introduce a lightweight and accurate localization method that only utilizes the geometry
of 2D-3D lines. Given a pre-captured 3D map our approach localizes a panorama image …

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 …

We propose a novel pipeline called Loc-PL that uses both points and lines for indoor visual
localization in dense colored point cloud. Loc-PL utilizes the spatially complementary …
