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 ...
High-resolution 360 Video Foveated Stitching for Real-time VR
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
In virtual reality (VR) applications, the contents are usually generated by creating a 360 video panorama of a real-world scene. Although many capture devices are being released, getting high-resolution panoramas and ...
Data-Driven Sparse Priors of 3D Shapes
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
We present a sparse optimization framework for extracting sparse shape priors from a collection of 3D models. Shape priors are defined as point-set neighborhoods sampled from shape surfaces which convey important information ...
Modeling Cumulus Cloud Scenes from High-resolution Satellite Images
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
We present a reconstruction framework, which fits physically-based constraints to model large-scale cloud scenes from satellite images. Applications include weather phenomena visualization, flight simulation, and weather ...
A Data-Driven Approach for Sketch-Based 3D Shape Retrieval via Similar Drawing-Style Recommendation
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Sketching is a simple and natural way of expression and communication for humans. For this reason, it gains increasing popularity in human computer interaction, with the emergence of multitouch tablets and styluses. In ...
