I am currently a PhD student at the Department of Automation, Tsinghua University, China, supervised by Prof. Yebin Liu. Prior to this, I received my Bachelor's degree in Mathematics from Tsinghua University.

Publications
Fast and Globally Consistent Normal Orientation based on the Winding Number Normal Consistency
Siyou Lin, Zuoqiang Shi, Yebin Liu
SIGGRAPH Asia 2024 (Journal)
Project page / Paper / Code

We present Winding Number Normal Consistency (WNNC) and an iterative algorithm that estimates globally consistent normal vectors. Our CUDA-based treecode-accelerated algorithm handles a million of points in half a minute.

LayGA: Layered Gaussian Avatars for Animatable Clothing Transfer
Siyou Lin, Zhe Li, Zhaoqi Su, Zerong Zheng, Hongwen Zhang, Yebin Liu
SIGGRAPH 2024 (Conference)
ACM DL / Project page / Paper

We present LayGA, a layered Gaussian avatar model based on Animatable Gaussians, with improved geometry and the ability of animatable clothing transfer.

Leveraging Intrinsic Properties for Non-Rigid Garment Alignment
Siyou Lin, Boyao Zhou, Zerong Zheng, Hongwen Zhang, Yebin Liu
ICCV 2023
CVF page / Project page / Paper / Supp / Code / Poster

We leverage intrinsic manifold properties and neural deformation fields and propose a coarse-to-fine two-stage method for non-rigid garment alignment, achieving wrinkle-level and texture-level alignment.

CaPhy: Capturing Physical Properties for Animatable Human Avatars
Zhaoqi Su, Liangxiao Hu, Siyou Lin, Hongwen Zhang, Shengping Zhang, Justus Thies, Yebin Liu
ICCV 2023
Project page / Paper

We present CaPhy, a novel method combining 3D-supervised training with unsupervised physics-based losses for reconstructing animatable human avatars. Caphy allows estimating the physical properties of garments and producing realistic dynamic clothing.

CloSET: Modeling Clothed Humans on Continuous Surface with Explicit Template Decomposition
Hongwen Zhang, Siyou Lin, Ruizhi Shao, Yuxiang Zhang, Zerong Zheng, Han Huang, Yandong Guo, Yebin Liu
CVPR 2023
Project page / Paper / Dataset

We present CloSET, a point-based human avatar modeling method that allows loose clothing modeling by explicit template decomposition. We also release a real-world capture dataset of clothed humans in various poses.

Learning Implicit Templates for Point-Based Clothed Human Modeling
Siyou Lin, Hongwen Zhang, Zerong Zheng, Ruizhi Shao, Yebin Liu
ECCV 2022
Project page / ECVA page / Paper / Supp / Code / Poster

We propose a First-Implicit-Then-Explicit (FITE) framework that combines the merits of both implicit and explicit representations for modeling human avatars in clothing.

Surface Reconstruction from Point Clouds without Normals by Parametrizing the Gauss Formula *
Siyou Lin, Dong Xiao, Zuoqiang Shi, Bin Wang
ACM Trans. Graph. 2022. Presented at SIGGRAPH 2023
Project page / Paper / Code / Fast-forward video / Slides (SIGGRAPH 2023)

We present Parametric Gauss Reconstruction (PGR), a method that reconstructs surfaces from point clouds without normals by parametrizing the Gauss formula.

*Work done while I was an undergraduate at the Department of Mathematical Sciences, Tsinghua University.
