Robust Loop Closure by Textual Cues in Challenging Environments [PDF]
IEEE Robotics and Automation LettersLoop closure is an important task in robot navigation. However, existing methods mostly rely on some implicit or heuristic features of the environment, which can still fail to work in common environments such as corridors, tunnels, and warehouses. Indeed,

Detecting Loop Closure with Scene Sequences
International Journal of Computer Vision, 2007 This paper is concerned with "loop closing" for mobile robots. Loop closing is the problem of correctly asserting that a robot has returned to a previously visited area. It is a particularly hard but important component of the Simultaneous Localization and Mapping (SLAM) problem.

Loop closure detection using depth images [PDF]
2013 European Conference on Mobile Robots, 2013 We investigate the question whether loop closure detection using depth images is feasible using currently available depth features. For this reason, we collected a benchmark dataset consisting of a total number of 15 logfiles with several loops in various environments, implemented a modular and easily extensible loop closure detector and used this to ...

LiPMatch: LiDAR Point Cloud Plane Based Loop-Closure [PDF]
IEEE Robotics and Automation Letters, 2020 This letter presents a point cloud based loop-closure method to correct long-term drifts in Light Detection and Ranging based Simultaneous Localization and Mapping systems. In the method, we formulate each keyframe as a fully-connected graph with nodes representing planes.

Loop Closure Detection in Closed Environments [PDF]
2019 European Conference on Mobile Robots (ECMR), 2019 Low cost robots, such as vacuum cleaners or lawn mowers employ simplistic and often random navigation policies. Although a large number of sophisticated mapping and planning approaches exist, they require additional sensors like LIDAR sensors, cameras or time of flight sensors.

Cooperativity in two-state protein folding kinetics [PDF]
, 2003 We present a solvable model that predicts the folding kinetics of two-state proteins from their native structures. The model is based on conditional chain entropies. It assumes that folding processes are dominated by small-loop closure events that can be

Visual Odometry and Place Recognition Fusion for Vehicle Position Tracking in Urban Environments
Sensors, 2018 In this paper, we address the problem of vehicle localization in urban environments. We rely on visual odometry, calculating the incremental motion, to track the position of the vehicle and on place recognition to correct the accumulated drift of visual ...
