Edge-Assisted Lightweight Region-of-Interest Extraction and Transmission for Vehicle Perception
Yan Cheng, Peng Yang, Ning Zhang +1
To enhance on-road environmental perception for autonomous driving, accurate and real-time analytics on high-resolution video frames generated from on-board cameras be-comes crucia…
SUPS: A Simulated Underground Parking Scenario Dataset for Autonomous Driving
Jiawei Hou, Qi Chen, Yurong Cheng +4
Automatic underground parking has attracted considerable attention as the scope of autonomous driving expands. The auto-vehicle is supposed to obtain the environmental information,…
Hierarchical Topometric Representation of 3D Robotic Maps
Zhenpeng He, Hao Sun, Jiawei Hou +2
In this paper, we propose a method for generating a hierarchical, volumetric topological map from 3D point clouds. There are three basic hierarchical levels in our map: $storey - r…
QA4PRF: A Question Answering based Framework for Pseudo Relevance Feedback
Handong Ma, Jiawei Hou, Chenxu Zhu +6
Pseudo relevance feedback (PRF) automatically performs query expansion based on top-retrieved documents to better represent the user's information need so as to improve the search…
U-rank: Utility-oriented Learning to Rank with Implicit Feedback
Xinyi Dai, Jiawei Hou, Qing Liu +6
Learning to rank with implicit feedback is one of the most important tasks in many real-world information systems where the objective is some specific utility, e.g., clicks and rev…
Self-supervised Point Set Local Descriptors for Point Cloud Registration
Yijun Yuan, Jiawei Hou, Andreas Nüchter +1
In this work, we propose to learn local descriptors for point clouds in a self-supervised manner. In each iteration of the training, the input of the network is merely one unlabele…
Fast 2D Map Matching Based on Area Graphs
Jiawei Hou, Haofei Kuang, Sören Schwertfeger
We present a novel area matching algorithm for merging two different 2D grid maps. There are many approaches to address this problem, nevertheless, most previous work is built on s…
Furniture Free Mapping using 3D Lidars
Zhenpeng He, Jiawei Hou, Sören Schwertfeger
Mobile robots depend on maps for localization, planning, and other applications. In indoor scenarios, there is often lots of clutter present, such as chairs, tables, other furnitur…
Area Graph: Generation of Topological Maps using the Voronoi Diagram
Jiawei Hou, Yijun Yuan, Sören Schwertfeger
Representing a scanned map of the real environment as a topological structure is an important research topic in robotics. Since topological representations of maps save a huge amou…
Topological Area Graph Generation and its Application to Path Planning
Jiawei Hou, Yijun Yuan, Sören Schwertfeger
Representing a scanned map of the real environment as a topological structure is an important research in robotics. %is currently an important research. Since topological represent…
