Biography.

BIOGRAPHY

I am currently a senior graphics engineer at Huawei, working on GoPaint. Before that, I received the Ph.D. degree from The Chinese University of Hong Kong (CUHK), supervised by Prof. Chi-Wing Fu; and the B.Eng. degree from the University of Science and Technology of China (USTC).
Now I am still super passionate about Computer Graphics. 3D Reconstruction, Virtual Reality / Augmented Reality and Human-Computer Interaction also fall within my research fields of interest.

OccluGaussian: Occlusion-Aware Gaussian Splatting for Large Scene Reconstruction and Rendering

Shiyong Liu*, Xiao Tang*, Zhihao Li*, Yingfan He, ChongJie Ye, Jianzhuang Liu, Binxiao Huang, Shunbo Zhou, Xiaofei Wu International Conference on Computer Vision (ICCV), 2025
We propose a scene-layout-aware division strategy for very large scenes, improving reconstruction quality and accelerating rendering.

SpecTRe-GS: Modeling Highly Specular Surfaces with Reflected Nearby Objects by Tracing Rays in 3D Gaussian Splatting

Jiajun Tang, Fan Fei, Zhihao Li, Xiao Tang, Shiyong Liu, Youyu Chen, Binxiao Huang, Zhenyu Chen, Xiaofei Wu, Boxin Shi The IEEE / CVF Computer Vision and Pattern Recognition Conference (CVPR), 2025 Highlight
We use 3D Gaussian ray tracing (3DGRT) to model surfaces with near-perfect reflections.

DashGaussian: Optimizing 3D Gaussian Splatting in 200 Seconds

Youyu Chen, Junjun Jiang, Kui Jiang, Xiao Tang, Zhihao Li, Xianming Liu, Yinyu Nie The IEEE / CVF Computer Vision and Pattern Recognition Conference (CVPR), 2025 Highlight
We achieve an average speedup of 45.7% for most 3DGS backbones while preserving or even improving reconstruction quality.

Decoupling Appearance Variations with 3D Consistent Features in Gaussian Splatting

Jiaqi Lin, Zhihao Li, Binxiao Huang, Xiao Tang, Jianzhuang Liu, Shiyong Liu, Xiaofei Wu, Fenglong Song, Wenming Yang The Association for the Advancement of Artificial Intelligence (AAAI), 2025
We decouple appearance variations, even between day and night, enabling effective 3DGS reconstruction.

MirrorGaussian: Reflecting 3D Gaussians for Reconstructing Mirror Reflections

Jiayue Liu*, Xiao Tang*, Freeman Cheng, Roy Yang, Zhihao Li, Jianzhuang Liu, Yi Huang, Jiaqi Lin, Shiyong Liu, Xiaofei Wu, Songcen Xu, Chun Yuan European Conference on Computer Vision (ECCV), 2024
