Qijian Tian

I'm a second-year Ph.D. student in Computer Science at Shanghai Jiao Tong University (SJTU), advised by Prof. Lizhuang Ma in Digital Media & Computer Vision Laboratory (DMCV). I also receive supervision from Dr. Xin Tan, who is based at East China Normal University (ECNU).

Prior to starting my PhD, I received my Bachelor's degree in Computer Science from Beihang University (BUAA). I also worked as an intern at Baidu .

Research

My research interests involve computer vision and deep learning. I am currently interested in 3D vision, including 3D scene reconstruction, 3D gaussian splatting, and depth estimation. I previously focused on 2D scene understanding, especially in scene parsing.
