3D Shape Segmentation and Labeling via Extreme Learning Machine
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We propose a fast method for 3D shape segmentation and labeling via Extreme Learning Machine (ELM). Given a set of example shapes with labeled segmentation, we train an ELM classifier and use it to produce initial segmentation ... -
Transductive 3D Shape Segmentation using Sparse Reconstruction
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We propose a transductive shape segmentation algorithm, which can transfer prior segmentation results in database to new shapes without explicitly specification of prior category information. Our method first partitions ... -
Designing N-PolyVector Fields with Complex Polynomials
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We introduce N-PolyVector fields, a generalization of N-RoSy fields for which the vectors are neither necessarily orthogonal nor rotationally symmetric. We formally define a novel representation for N-PolyVectors as the ... -

Efficient Encoding of Texture Coordinates Guided by Mesh Geometry
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this paper, we investigate the possibilities of efficient encoding of UV coordinates associated with vertices of a triangle mesh. Since most parametrization schemes attempt to achieve at least some level of conformality, ... -
Blue-Noise Remeshing with Farthest Point Optimization
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this paper, we present a novel method for surface sampling and remeshing with good blue-noise properties. Our approach is based on the farthest point optimization (FPO), a relaxation technique that generates high quality ... -
Learnt Real-time Meshless Simulation
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a new real-time approach to simulate deformable objects using a learnt statistical model to achieve a high degree of realism. Our approach improves upon state-of-the-art interactive shape-matching meshless ... -
An Efficient Approach to Correspondences between Multiple Non-Rigid Parts
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Identifying multiple deformable parts on meshes and establishing dense correspondences between them are tasks of fundamental importance to computer graphics, with applications to e.g. geometric edit propagation and texture ... -
Supervised Learning of Bag-of-features Shape Descriptors Using Sparse Coding
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a method for supervised learning of shape descriptors for shape retrieval applications. Many contentbased shape retrieval approaches follow the bag-of-features (BoF) paradigm commonly used in text and image ... -
3D Motion Completion in Crowded Scenes
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Crowded motions refer to multiple objects moving around and interacting such as crowds, pedestrians and etc. We capture crowded scenes using a depth scanner at video frame rates. Thus, our input is a set of depth frames ... -
Clever Support: Efficient Support Structure Generation for Digital Fabrication
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We introduce an optimization framework for the reduction of support structures required by 3D printers based on Fused Deposition Modeling (FDM) technology. The printers need to connect overhangs with the lower parts of the ... -
What Makes London Work Like London?
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Urban data ranging from images and laser scans to traffic flows are regularly analyzed and modeled leading to better scene understanding. Commonly used computational approaches focus on geometric descriptors, both for ... -
Real-time Bas-Relief Generation from Depth-and-Normal Maps on GPU
(The Eurographics Association and John Wiley and Sons Ltd., 2014)To design a bas-relief from a 3D scene is an inherently interactive task in many scenarios. The user normally needs to get instant feedback to select a proper viewpoint. However, current methods are too slow to facilitate ... -
Pattern-Based Quadrangulation for N-Sided Patches
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We propose an algorithm to quadrangulate an N-sided patch with prescribed numbers of edge subdivisions at its boundary. Our algorithm is guaranteed to succeed for arbitrary valid input, which is proved using a canonical ... -
Discrete 2-Tensor Fields on Triangulations
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Geometry processing has made ample use of discrete representations of tangent vector fields and antisymmetric tensors (i.e., forms) on triangulations. Symmetric 2-tensors, while crucial in the definition of inner products ... -
Robust Region Detection via Consensus Segmentation of Deformable Shapes
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We consider the problem of stable region detection and segmentation of deformable shapes. We pursue this goal by determining a consensus segmentation from a heterogeneous ensemble of putative segmentations, which are ... -
Compressed Manifold Modes for Mesh Processing
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper introduces compressed eigenfunctions of the Laplace-Beltrami operator on 3D manifold surfaces. They constitute a novel functional basis, called the compressed manifold basis, where each function has local support. ... -
Piecewise-Planar 3D Reconstruction with Edge and Corner Regularization
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper presents a method for the 3D reconstruction of a piecewise-planar surface from range images, typically laser scans with millions of points. The reconstructed surface is a watertight polygonal mesh that conforms ... -
Feature-Preserving Surface Completion Using Four Points
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a user-guided, semi-automatic approach to completing large holes in a mesh. The reconstruction of the missing features in such holes is usually ambiguous. Thus, unsupervised methods may produce unsatisfactory ... -
Freeform Honeycomb Structures
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Motivated by requirements of freeform architecture, and inspired by the geometry of hexagonal combs in beehives, this paper addresses torsion-free structures aligned with hexagonal meshes. Since repetitive geometry is a ...
