QuestEnvSim: Environment-Aware Simulated Motion Tracking from Sparse Sensors

no code implementations9 Jun 2023 Sunmin Lee, Sebastian Starke, Yuting Ye, Jungdam Won, Alexander Winkler

Most existing methods for motion tracking avoid environment interaction apart from foot-floor contact due to their complex dynamics and hard constraints.

AlteredAvatar: Stylizing Dynamic 3D Avatars with Fast Style Adaptation

no code implementations30 May 2023 Thu Nguyen-Phuoc, Gabriel Schwartz, Yuting Ye, Stephen Lombardi, Lei Xiao

Among existing approaches for avatar stylization, direct optimization methods can produce excellent results for arbitrary styles but they are unpleasantly slow.

Decision Making for Hierarchical Multi-label Classification with Multidimensional Local Precision Rate

no code implementations16 May 2022 Yuting Ye, Christine Ho, Ci-Ren Jiang, Wayne Tai Lee, Haiyan Huang

We show that classification decisions made by simply sorting objects across classes in descending order of their true mLPRs can, in theory, ensure the class hierarchy and lead to the maximization of CATCH, an objective function we introduce that is related to the area under a hit curve.

Identity-Disentangled Neural Deformation Model for Dynamic Meshes

no code implementations30 Sep 2021 Binbin Xu, Lingni Ma, Yuting Ye, Tanner Schmidt, Christopher D. Twigg, Steven Lovegrove

When applied to dynamically deforming shapes such as the human hands, however, they would need to preserve temporal coherence of the deformation as well as the intrinsic identity of the subject.
