Zhiwei Zhu (朱志伟)

I am currently a PhD candidate at the College of Information Science and Electronic Engineering of Zhejiang University (ZJU) (2021-Present), supervised by Prof. Lu Yu, with guidance from Asst. Prof. Yiyi Liao.
I got my B.Eng. degree in Electronic Information Engineering at the Qiushi Honors College (now known as the College of Future Technology) of Tianjin University (TJU) in 2021.
My research interests lie in 3D computer vision and visual data compression.
