Ke XU许 可 Research Fellow City University of Hong Kong Email: kkangwing at gmail dot com |
I currently work at the City University of Hong Kong. I obtained a dual PhD in Computer Science from Dalian University of Technology and City University of Hong Kong in 2021. My research interest lies at the intersection of computer vision, computer graphics, and machine learning, where I explore advanced AI techniques to facilitate computers to see, understand, and recreate the richness of content in everyday and professional activities. My work addresses challenges of capture and learning, including imaging and building effective representations under harsh conditions (e.g., low and/or high illumination, rain, and sparse capture rigs) at varying time/scene/data scales. My research papers generally appear in premier venues featuring computer vision, graphics, and machine learning (e.g., CVPR/SIGGRAPH (Asia)/NeurIPS).
