Research
I'm interested in multi-sensor fusion for object detection and visual place recognition. I also research on techniques for optimising performance and speed for real-world implementations on various platforms. Representative paper(s) are highlighted.

Hot-NetVLAD: Learning discriminatory key points for visual place recognition Zhikai Li, Christina Dao Wen Lee*, Beatrix Xue Lin Tung, Zefan Huang, Daniela Rus, Marcelo H Ang RAL, 2023 paper Hot-NetVLAD implements a hot-spot detector on a learned local key-patch descriptor algorithm for Visual Place Recognition (VPR), thereby greatly cutting down the size of features extracted. Furthermore, identified hot-spots bring new insights to key regions required for VPR, as they tend to fall on distinguishable static objects in the scene. |

Online obstacle trajectory prediction for autonomous buses Yue Linn Chong, Christina Dao Wen Lee*, Liushifeng Chen, Chongjiang Shen, Ken Kok Hoe Chan, Marcelo H Ang Jr Machines, 2022 Feature Paper SGAB Dataset / paper
In this paper, we present the development of a modular pipeline for the long-term prediction of dynamic obstacles’ trajectories for an autonomous bus. Our Singapore autonomous bus (SGAB) dataset evaluated the pipeline’s performance. The dataset is publicly available online.
