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 ...
Spatial Matching of Animated Meshes
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
This paper presents a new technique which makes use of deformation and motion properties between animated meshes for finding their spatial correspondences. Given a pair of animated meshes exhibiting a semantically similar ...
An Eulerian Approach for Constructing a Map Between Surfaces With Different Topologies
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
3D objects of the same kind often have different topologies, and finding correspondence between them is important for operations such as morphing, attribute transfer, and shape matching. This paper presents a novel method ...
Efficient Volumetric PolyCube-Map Construction
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
PolyCubes provide compact representations for closed complex shapes and are essential to many computer graphics applications. Existing automatic PolyCube construction methods usually suffer from poor quality or time-consuming ...
Harmonic Functions for Rotational Symmetry Vector Fields
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Representing rotational symmetry vector as a set of vectors is not suitable for design due to lacking of a consistent ordering for measurement. In this paper we introduce a spectral method to find rotation invariant harmonic ...
Automatic Modeling of Urban Facades from Raw LiDAR Point Data
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Modeling of urban facades from raw LiDAR point data remains active due to its challenging nature. In this paper, we propose an automatic yet robust 3D modeling approach for urban facades with raw LiDAR point clouds. The ...
Building Construction Sets by Tiling Grammar Simplification
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
This paper poses the problem of fabricating physical construction sets from example geometry: A construction set provides a small number of different types of building blocks from which the example model as well as many ...
Learning 3D Deformation of Animals from 2D Images
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Understanding how an animal can deform and articulate is essential for a realistic modification of its 3D model. In this paper, we show that such information can be learned from user-clicked 2D images and a template 3D ...
Mesh Statistics for Robust Curvature Estimation
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
While it is usually not difficult to compute principal curvatures of a smooth surface of sufficient differentiability, it is a rather difficult task when only a polygonal approximation of the surface is available, because ...
