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

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.

Research

Much of my research is about inferring the physical world (shape, motion, color, etc) from images and 3D raw data.

CSG-Fusion: Consistent Sparse-View Gaussian Splatting via Matching-based Fusion

Yan Xia*, Wenbo Ji*, Weirong Chen, Daniel Cremers

ICCV E2E3D Workshop, 2025

A feed-forward framework that mindfully integrates pixel-aligned pointmap to reduce redundant primitives and produce compact and consistent 3D structures.

LiteTracker: Leveraging Temporal Causality for Accurate Low-latency Tissue Tracking

Mert Asim Karaoglu, Wenbo Ji, Ahmed Abbas,
Nassir Navab, Benjamin Busam, Alexander Ladikos

MICCAI, 2025

A low-latency method for tissue online tracking in endoscopic video streams, introduces a set of training-free runtime optimizations on a state-of-the-art long-term point tracking method.

RE0: Recognize Everything with 3D Zero-shot Instance Segmentation

Xiaohan Yan*, Zijian Jiang*, Yinghao Shuai*, Nan Wang, Xiaowei Song,
Wenbo Ji, Ge Wu, Jinyu He, Gang Wei, Zhicheng Wang

ICRA, 2025

Given 3D point clouds and multi-view RGB-D images with poses, Re0 leverages the 3D geometric information, projection relationships and CLIP semantic features for 3D zero-shot instance segmentation.
