About Me

Hi, I am Runsong Zhu (朱润松), a fourth-year PhD student in CSE, the Chinese University of Hong Kong, supervised by Prof. Chi-Wing Fu, Philip and Prof. Pheng-Ann Heng. Before that, I received my master's degree in LIESMARS, Wuhan University supervised by Prof. Bisheng Yang and Prof. Zhen Dong in 2022 and bachelor's degree in Central South University in 2019.

Research interests: I am interested in computer vision and computer graphics. My research began with point cloud analysis (e.g., normal estimation, surface reconstruction). I then explored projects on 3D semantic reconstruction from multi-view image inputs. More recently, I have been working on feedforward semantic reconstruction and a robotics-related project.
