Fusion of semantic and appearance features for loop‐closure detection in a dynamic environment
Electronics Letters, 2021 Loop‐closure detection is important in large‐scale localisation system. However, it is still difficult in a dynamic environment. An online fast loop‐closure detection algorithm based on Deeplabv3 with MobileNetV2 (DpMn2) as network backbone and local ...

Protein Loop Closure Using Orientational Restraints from NMR Data [PDF]
Proteins: Structure, Function, and Bioinformatics, 2011 AbstractProtein loops often play important roles in biological functions. Modeling loops accurately is crucial to determining the functional specificity of a protein. Despite the recent progress in loop prediction approaches, which led to a number of algorithms over the past decade, few rigorous algorithmic approaches exist to model protein loops using

Loop Closure Detection Based on Differentiable Manifold
Mobile Information Systems, 2022 Loop closure detection is an important part of SLAM (simultaneous location and mapping), which can effectively reduce the cumulative error of the system after long period of exploration. The existing loop closure detection methods are mainly to evenly distribute the accumulated error in the robot trajectory, but the motion error of the actual robot is ...

Loop Closure Detection Based on Image Semantic Segmentation in Indoor Environment
Mathematical Problems in Engineering, 2022 When mobile robots run in indoor environment, a large number of similar images are easy to appear in the images collected, probably causing false-positive judgment in loop closure detection based on simultaneous localization and mapping (SLAM).

Robust Photogeometric Localization over Time for Map-Centric Loop Closure
, 2019 Map-centric SLAM is emerging as an alternative of conventional graph-based SLAM for its accuracy and efficiency in long-term mapping problems. However, in map-centric SLAM, the process of loop closure differs from that of conventional SLAM and the result

Lazy localization using the Frozen-Time Smoother [PDF]
, 2008 We present a new algorithm for solving the global localization problem called Frozen-Time Smoother (FTS). Time is 'frozen', in the sense that the belief always refers to the same time instant, instead of following a moving target, like Monte Carlo ...
