🧐 About Me
I am a Master’s student in Computer Science at ETH Zürich, where I am currently working on a research project in the Computer Vision and Geometry Group (CVG) mentored by Boyang Sun and advised by Prof. Dr. Marc Pollefeys and Dr. Hermann Blum. Previously, I worked on a semester project at the Advanced Interactive Technologies (AIT) Lab under the supervision of Prof. Dr. Otmar Hilliges. I obtained my Bachelor’s degree from The University of Sydney. My research interests include computer vision, particularly 3D vision (e.g., reconstruction and robotics applications) and generative AI.

ActLoc: Learning to Localize on the Move via Active Viewpoint Selection
[Conference on Robot Learning (CoRL) 2025]
Jiajie Li*, Boyang Sun*, Luca Di Giammarino, Hermann Blum, Marc Pollefeys
TL;DR: ActLoc learns from SfM maps to predict, at each waypoint, a distribution of localization accuracy over multiple yaw–pitch angles (a LocMap), then uses it in planning to pick camera orientations that improve localization reliability under motion constraints, with real-time inference.
EgoGaussian: Dynamic Scene Understanding from Egocentric Video with 3D Gaussian Splatting
[International Conference on 3D Vision (3DV) 2025]
Daiwei Zhang, Gengyan Li, Jiajie Li, Mickaël Bressieux, Otmar Hilliges, Marc Pollefeys, Luc Van Gool, Xi Wang
TL;DR: From a single egocentric RGB video, EgoGaussian jointly reconstructs the static scene and tracks rigid objects by representing them with explicit 3D Gaussian sets and optimizing per-frame object poses, yielding high-quality novel view synthesis without depth sensors or object models.
