Simultaneous Detection of Loop-Closures and Changed Objects
Journal of Advanced Computational Intelligence and Intelligent Informatics, 2022 Loop-closure detection (LCD) in large non-stationary environments remains an important challenge in robotic visual simultaneous localization and mapping (vSLAM). To reduce computational and perceptual complexity, it is helpful if a vSLAM system has the ability to perform image change detection (ICD).

Beyond SIFT using binary features in Loop Closure Detection [PDF]
2017 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2017 In this paper a binary feature based Loop Closure Detection (LCD) method is proposed, which for the first time achieves higher precision-recall (PR) performance compared with state-of-the-art SIFT feature based approaches. The proposed system originates from our previous work Multi-Index hashing for Loop closure Detection (MILD), which employs Multi ...
