Position-based Skin Deformations for Interactive Character Animation
(2016-03-03)
Skeletal animation is a widely used technique for animating articulated characters, such as humans and animals. In skeleton-based animation, skinning is the process of defining how the geometric surface of the character ...
Interactive, Example-driven Synthesis and Manipulation of Visual Media
(2016-12-02)
This thesis proposes several novel techniques for interactive, example-driven synthesis and
manipulation of visual media. The numerous display devices in our everyday lives make
visual media, such as images, videos, or ...
From motion capture to interactive virtual worlds: towards unconstrained motion-capture algorithms for real-time performance-driven character animation
(2016-12-15)
This dissertation takes performance-driven character animation as a representative application and advances motion capture algorithms and animation methods to meet its high demands. Existing approaches have either coarse ...
Tracking Hands in Action for Gesture-based Computer Input
(2016-12-16)
This thesis introduces new methods for markerless tracking of the full articulated motion of hands and for informing the design of gesture-based computer input. Emerging devices such as smartwatches or virtual/augmented ...
Exploring Online Learners' Interactive Dynamics by Visually Analyzing Their Time-anchored Comments
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
MOOCs (Massive Open Online Courses) are increasingly prevalent as an online educational resource open to everyone and have attracted hundreds of thousands learners enrolling these online courses. At such scale, there is ...
Photometric Stabilization for Fast-forward Videos
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Videos captured by consumer cameras often exhibit temporal variations in color and tone that are caused by camera autoadjustments like white-balance and exposure. When such videos are sub-sampled to play fast-forward, as ...
Group Representation of Global Intrinsic Symmetries
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Global intrinsic symmetry detection of 3D shapes has received considerable attentions in recent years. However, unlike extrinsic symmetry that can be represented compactly as a combination of an orthogonal matrix and a ...
Modeling, Evaluation and Optimization of Interlocking Shell Pieces
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
While the 3D printing technology has become increasingly popular in recent years, it suffers from two critical limitations: expensive printing material and long printing time. An effective solution is to hollow the 3D model ...
Patch2Vec: Globally Consistent Image Patch Representation
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Many image editing applications rely on the analysis of image patches. In this paper, we present a method to analyze patches by embedding them to a vector space, in which the Euclidean distance reflects patch similarity. ...
Rib-reinforced Shell Structure
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Shell structures are extensively used in engineering due to their efficient load-carrying capacity relative to material volume. However, large-span shells require additional supporting structures to strengthen fragile ...
