Foot & Ankle Surgery: Techniques, Reports & Cases, 2022 Treating necrotizing diabetic infections can lead to significant loss of skin and soft tissue, making primary closure ill-advised. Managing large diabetic wounds is challenging and more so in community hospitals with limited resources and specialists.1 ...

LiDAR Iris for Loop-Closure Detection [PDF]
2020 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2020 In this paper, a global descriptor for a LiDAR point cloud, called LiDAR Iris, is proposed for fast and accurate loop-closure detection. A binary signature image can be obtained for each point cloud after several LoG-Gabor filtering and thresholding operations on the LiDAR-Iris image representation.

Lightweight Unsupervised Deep Loop Closure
Robotics: Science and Systems XIV, 2018 Robust efficient loop closure detection is essential for large-scale real-time SLAM. In this paper, we propose a novel unsupervised deep neural network architecture of a feature embedding for visual loop closure that is both reliable and compact. Our model is built upon the autoencoder architecture, tailored specifically to the problem at hand.

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.
