A Virtual Try-on System for Prescription Eyeglasses
Qian Zhang, Yu Guo, Pierre-Yves Laffont, Tobias Martin, Markus Gross
Computer Graphics and Application, 2017 [Paper][Video]

We present a system for virtual try-on of prescription eyeglasses. Compared to existing virtual try-on systems, our approach simulates the refraction effects due to the corrective lens and takes into account reflections and shading.

3D Faces are Recognized More Accurately and Faster than 2D Faces, but with Similar Inversion Effects
Derric Eng, Belle Yick, Yu Guo, Hong Xu, Miriam Reiner, TJ Cham, SH Chen
Vision Research, 2017 [Paper]

We present an experiment to indicate that 3D faces would be recognised with shorter reaction time (RT) and greater accuracy than 2D faces during holistic and featural processing.

Physically Based Video Editing
Jean-Charles Bazin, Claudia Pluss, Yu Guo, Tobias Martin, Alec Jacobson, Markus Gross
Computer Graphics Forum (Present on PG'16), 2016 [Paper][Video]

We propose a framework that combines video editing and physics-based simulation. Our tool assists unskilled users in editing an input image or video while respecting the laws of physics and also leveraging the image content.

GPU Accelerated CBCT Reconstruction From Few Views with SART and TV Regularization
Ping Liu, Lin Shi, Defeng Wang, Yu Guo, Jianying Li, Jing Qin, Pheng-Ann Heng
HPC-MICCAI'13, Japan [Paper]

We implemented an GPU-based algorithm by combining simultaneous algebraic reconstruction technique (SART) and total variation (TV) regularization for the CBCT reconstruction from few views.

Real-time Hand Detection Based on Multi-stage HOG-SVM Classifier
Jiang Guo, Jun Cheng, Jianxin Pang, Yu Guo
ICIP'13, Australia [Paper]

We proposed a real-time hand detection method multi-stage classifier which combines several SVM classifies, each of which is trained to distinguish corresponding divisions of background and target.

A GPU-accelerated Finite Element Solver for Simulation of Soft-body Deformation
Yu Guo, Jianying Li, Ping Liu, Qiong Wang, Jing Qin
ICIA'13, China [Paper]

We presented a simulation method of soft body deformation with GPU implementation, which based on Delaunay Tetrahedralizition, Finite Element Method with friction-based collisional model.

A Survey on Simulation of Soft Tissue Deformation in Virtual Surgery (in Chinese)
Yu Guo, Jing Qin
Journal of Integration Technology, 2013 [Paper]

This paper presents a comprehensive survey on simulation of soft tissue deformation in virtual surgery. Including geometrically-based methods and physically-based methods, mesh-based model and meshless model.

Fall Over or Sliding Down?
Yu Guo.
SIGGRAPH Asia'12 (Poster) , Singapore [Paper] [Poster]

We presented a contact model depending on constraints coupled with frictions which is called portable frictional contact model.

A Master-Slave Robotic Simulator Based on GPUDirect
Jianying Li, Yu Guo, Heye Zhang, Yongming Xie
IROS'12, Portugal [Paper]

We presented a master-slave robotic simulator by using GPUDirect with InfiniBand card to speed up data transmission.
