Real-time Video-based Facial Performance Capture and ManipulationAutomatic algorithms to real-time capture 3D high-quality facial mesh sequences as well as video-based facial expression manipulation and face swapping
Analysis and Modeling Human Behaviors in Multiparty ConversationsQuantifying, understanding, and modeling human behaviors and gestures when they are involved with multiparty conversations
Skeletal Rigging from Mesh/Point SequencesUsing the input of an animated mesh sequence, this approach can automatically extract its optimal skeleton structure, joint positions, linear blend skinning weights, and the corresponding bone transformations.
Crowd Simulation and EvacuationNew algorithms and systems to simulate crowds or group behavior in unexpected hazard situations, computational model of crowd emotion evolution, or simulated crowds by integrating physical strength consumption
Visual Traffic Simulation, Modeling, and EvaluationDesign of novel and efficient algorithms and systems to simulate large-scale realistic traffic in various road and urban settings, including mixed traffic, lane-changing, simulated traffic evaluation, and intersectional traffic simulation.
3D Face Modeling from In-the-wild Images or VideoAutomatic methods to reconstruct 3D face models with fine-scale details from a single in-the-wild image or video, including automatically augment coarse-scale 3D faces with synthesized fine-scale geometric wrinkles.
Data-driven Guzheng Playing AnimationA fully automatic, deep learning based framework to synthesize realistic upper body animations based on novel Guzheng music input. We design a generative adversarial network based approach to capture the temporal relationship between Guzheng music and human motion.
Hexahedral Mesh Generation, Optimization, and EvaluationA first and complete pipeline to optimize the global structure of a hex-mesh, by identifying and removing those valid removal base-complex sheets that contain misaligned singularities, and a volumetric partitioning strategy based on a generalized sweeping framework to seamlessly partition the volume of an input triangle mesh into a collection of deformed cuboids.
Interactive Complex Object Modeling from Multi-view Imagesdevelopment of a novel interactive modeling approach based on multi-view images including interactive 3D modeling and stochastic motion parameter estimation.
