Towards Accurate Loop Closure Detection in Semantic SLAM with 3D Semantic Covisibility Graphs
Zhentian Qian, Jie Fu, Jing Xiao
Loop closure is necessary for correcting errors accumulated in simultaneous localization and mapping (SLAM) in unknown environments. However, conventional loop closure methods base…
One-shot Joint Extraction, Registration and Segmentation of Neuroimaging Data
Yao Su, Zhentian Qian, Lei Ma +2
Brain extraction, registration and segmentation are indispensable preprocessing steps in neuroimaging studies. The aim is to extract the brain from raw imaging scans (i.e., extract…
Topology-Guided Modular Actor-Critic Learning for Continuous Systems under Temporal Objectives
Lening Li, Zhentian Qian, Jianan Xia +7
We study formal policy synthesis for continuous-state stochastic systems under linear temporal logic specifications. The product of the system with the automaton of the specificati…
Autonomous Search of Semantic Objects in Unknown Environments
Zhentian Qian, Jie Fu, Jing Xiao
This paper addresses the problem of enabling a robot to search for a semantic object, i.e., an object with a semantic label, in an unknown and GPS-denied environment. For the robot…
