Wenbo Ji   jī / yí文博

I am a second year master's student in Electrical Engineering and Information Technology at the Technical University of Munich.

I am doing research internship with Jiapeng Tang and Prof. Matthias Nießner at TUM Visual Computing Group.

I was working as a working student at ImFusion with Mert Asim Karaoglu, Dr. Benjamin Busam, Prof. Nassir Navab.

I was a master's student of TUM-CVG, TUM-DI-LAB working with Prof. Daniel Cremers, Dr. Yan Xia, Dr. Chuanxia Zheng and Weirong Chen.

I did a research internship at Zhejiang University under the supervision of Prof. Yiyi Liao.

I obtained my Master's degree in Computer Science from the Tongji University.

I did my B.Sc. in Information and Computing Science at Nanjing Tech University.

My research interests lie at the intersection of computer vision, computer graphics, and machine learning -- creating virtual human models and representing 3D scenes.

If you find any research interests that we might share, feel free to drop me an email.

Thesis
4D Half Gaussian Splatting based Endoscopic Stereo Scene Reconstruction

Tongji University Master's Thesis, 2025

3D/4D Reconstruction

Given stereo endoscopic videos of deformable tissues, this thesis proposes a 4D deformable half-Gaussian splatting framework with depth-prior initialization, temporal–spatial encoding, and lightweight Gaussian pruning for high-fidelity, real-time surgical scene reconstruction.
