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.
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.
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.
