Overview + Detail Visualization for Ensembles of Diffusion Tensors
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
A Diffusion Tensor Imaging (DTI) group study consists of a collection of volumetric diffusion tensor datasets (i.e., an ensemble) acquired from a group of subjects. The multivariate nature of the diffusion tensor imposes ...
Computing Contour Trees for 2D Piecewise Polynomial Functions
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Contour trees are extensively used in scalar field analysis. The contour tree is a data structure that tracks the evolution of level set topology in a scalar field. Scalar fields are typically available as samples at ...
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 ...
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 ...
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 ...
Regression-Based Landmark Detection on Dynamic Human Models
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Detecting anatomical landmarks on various human models with dynamic poses remains an important and challenging problem in computer graphics research. We present a novel framework that consists of two-level regressors for ...
Semi-Automatic Conversion of 3D Shape into Flat-Foldable Polygonal Model
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
This paper presents a method that can convert a given 3D mesh into a flat-foldable model consisting of rigid panels. A previous work proposed a method to assist manual design of a single component of such flat-foldable ...
