Angle-Displacement Rigidity Theory with Application to Distributed Network Localization

no code implementations19 Dec 2023 Xu Fang, Xiaolei Li, Lihua Xie

This paper investigates the localization problem of a network in 2-D and 3-D spaces given the positions of anchor nodes in a global frame and inter-node relative measurements in local coordinate frames.

Distributed Semi-global Output Feedback Formation Maneuver Control of High-order Multi-agent Systems

no code implementations19 Dec 2023 Xu Fang, Lihua Xie

Compared with existing relative-measurement-based formation maneuver control, the advantages of the proposed method are that it is output (relative output) feedback based and shows how to realize different types of formation shape.

3-D Distributed Localization with Mixed Local Relative Measurements

no code implementations18 Dec 2023 Xu Fang, Xiaolei Li, Lihua Xie

Each node holds a local coordinate frame without a common orientation and can only measure one type of information (relative position, distance, relative bearing, angle, or ratio-of-distance measurements) about its neighboring nodes in its local coordinate frame.

Distributed Localization in Dynamic Networks via Complex Laplacian

no code implementations18 Dec 2023 Xu Fang, Lihua Xie, Xiaolei Li

Different from most existing distributed localization approaches in static networks where the agents in a network are static, this paper addresses the distributed localization problem in dynamic networks where the positions of the agents are time-varying.

MCFNet: Multi-scale Covariance Feature Fusion Network for Real-time Semantic Segmentation

no code implementations12 Dec 2023 Xiaojie Fang, Xingguo Song, Xiangyin Meng, Xu Fang, Sheng Jin

The low-level spatial detail information and high-level semantic abstract information are both essential to the semantic segmentation task.

Distributed Formation Maneuver Control Using Complex Laplacian

no code implementations7 Dec 2023 Xu Fang, Lihua Xie

The third advantage is that more formation shapes can be realized by only tuning the positions of the leaders.

Integrated Relative-Measurement-Based Network Localization and Formation Maneuver Control (Extended Version)

no code implementations28 Oct 2023 Xu Fang, Lihua Xie, Xiaolei Li

This paper studies the problem of integrated distributed network localization and formation maneuver control.

A deep local attention network for pre-operative lymph node metastasis prediction in pancreatic cancer via multiphase CT imaging

no code implementations4 Jan 2023 Zhilin Zheng, Xu Fang, Jiawen Yao, Mengmeng Zhu, Le Lu, Lingyun Huang, Jing Xiao, Yu Shi, Hong Lu, Jianping Lu, Ling Zhang, Chengwei Shao, Yun Bian

Lymph node (LN) metastasis status is one of the most critical prognostic and cancer staging factors for patients with resectable pancreatic ductal adenocarcinoma (PDAC), or in general, for any types of solid malignant tumors.

Cooperative Pursuit with Multi-Pursuer and One Faster Free-moving Evader

1 code implementation IEEE Transactions on Cybernetics 2020 Xu Fang, Chen Wang, Lihua Xie, Jie Chen

When the faster evader is allowed to move freely without any constraint, the main issues are how to form an encirclement to trap the evader into the capture domain, how to balance between forming an encirclement and approaching the faster evader, and what conditions make the capture possible.

Model-free Approach for Sensor Network Localization with Noisy Distance Measurement

1 code implementation18 Nov 2018 Xu Fang, Chen Wang, Thien-Minh Nguyen, Lihua Xie

In addition, different from the traditional filter-based localization methods which need kinetic model for localization, our proposed method is model-free and converts the localization problem to graph optimization problem.

Graph Optimization Approach to Range-based Localization

1 code implementation28 Feb 2018 Xu Fang, Chen Wang, Thien-Minh Nguyen, Lihua Xie

In this paper, we propose a general graph optimization based framework for localization, which can accommodate different types of measurements with varying measurement time intervals.
