Welcome!

I am Xiaoyu Zhang (张啸宇), a fourth year PhD student from The Chinese University of Hong Kong (CUHK), under the supervision of Prof.Yun-Hui Liu. I got my master and bachelor degree from Beihang University (BUAA), advised by Prof.Wei Wang. I am also fortunate to work with Dr.Ji Zhao and Prof.Shiyu Zhao.

My research interests include computer vision in self-driving, SLAM and robotics.
