Robust and Accurate Skeletal Rigging from Mesh 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.
Two-layer Sparse Compression of Dense-Weight Blend SkinningIt introduces an efficient two-layer sparse compression technique to substantially reduce the computational cost of a dense-weight skinning model, with insignificant loss of its visual quality.
Smooth Skinning Decomposition with Rigid BonesThe SSDR model can effectively approximate the skin deformation of nearly articulated models as well as highly deformable models by a low number of rigid bones and a sparse, convex bone-vertex weight map.
Perceptually Guided Facial AnimationA perceptually guided computational framework is introduced to generate expressive facial animation, and quantitatively and automatically evaluate visual speech animation.
Eye and Head AnimationsData-driven synthesis algorithms for realistic and coordinated eye and head movements based on (live or pre-recorded) speech input
Visual Speech Animation SynthesisAutomated algorithms and systems to generate expressive visual speech animations based on novel typed or spoken input
Blendshape Facial AnimationAlgorithms for automating or reducing time-consuming tuning efforts of the blendshape animation approach, including target interference reducing, cross-model mapping, and model construction.
Human Motion Compression and RetrievalEffective algorithms for compressing and retrieving character motions by hierarchically extracting meaningful motion patterns from dataset, or by performing sparse dictionary learning from dataset.
Visual-Haptic Interfacing for Robot-Assisted Minimally Invasive Cardiac SurgeryA novel human-in-the-loop, visual haptic interfacing system for planning and performing real-time MRI guided, robot-assisted, minimally invasive surgical interventions on the beating heart, with particular focus on aortic valve implantations.
