Wenbo Ji   ĺµ‡jÄ« / yí文博

I am currently pursuing a second M.Sc. in Electrical Engineering and Information Technology at the Technical University of Munich. At TUM, I am working on my master's thesis on human motion video diffusion with Yu Chi, Jiapeng Tang, and Prof. Matthias NieĂźner at the TUM Visual Computing Group. In parallel, I am an intern at Agile Robots SE, where I work with Mahdi Hamad on video-action world models for robot dexterous manipulation.

My previous research and industry experience includes a research internship at TUM Visual Computing with Jiapeng Tang and Prof. Matthias NieĂźner, a working student position at ImFusion with Mert Asim Karaoglu, Prof. Benjamin Busam, Prof. Nassir Navab, as well as research at TUM-CVG and Oxford VGG with Prof. Daniel Cremers, Prof. Yan Xia, Prof. Chuanxia Zheng and Weirong Chen. I also completed a research internship at Zhejiang University under the supervision of Prof. Yiyi Liao.

Before joining TUM, I earned an M.Sc. in Computer Science from Tongji University and a B.Sc. in Information and Computing Science from Nanjing Tech University.

Research Interests

My research interests focus on moving beyond isolated visual subproblems toward integrated models of virtual humans and 3D scenes that can perceive, generate, and reason about interaction in dynamic environments.

Endoscopic Scene Reconstruction with 4D Half Gaussian Splatting 2025
Master's Thesis 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.
