Mesh Saliency Analysis via Local Curvature Entropy
(The Eurographics Association, 2016)
We present a novel approach for estimating mesh saliency. Our method is fast, flexible, and easy to implement. By applying the well-known concept of Shannon entropy to 3D mesh data, we obtain an efficient method to determine ...
Landmark-Guided Elastic Shape Analysis of Spherically-Parameterized Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We argue that full surface correspondence (registration) and optimal deformations (geodesics) are two related problems and propose a framework that solves them simultaneously. We build on the Riemannian shape analysis of ...
Geometric Flows of Curves in Shape Space for Processing Motion of Deformable Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
We introduce techniques for the processing of motion and animations of non-rigid shapes. The idea is to regard animations of deformable objects as curves in shape space. Then, we use the geometric structure on shape space ...
A Segmentation Transfer Method for Articulated Models
(The Eurographics Association, 2013)
In this paper, we propose using a pre-segmented example model to perform semantic-oriented segmentation of non-rigid 3D models of the same class (human, octopus, quadrupeds, etc.). Using the fact that the same type of ...
Optimal Spline Approximation via l0-Minimization
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Splines are part of the standard toolbox for the approximation of functions and curves in Rd. Still, the problem of finding the spline that best approximates an input function or curve is ill-posed, since in general this ...
A Data-Driven Approach to Realistic Shape Morphing
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Morphing between 3D objects is a fundamental technique in computer graphics. Traditional methods of shape morphing focus on establishing meaningful correspondences and finding smooth interpolation between shapes. Such ...
Space-Time Co-Segmentation of Articulated Point Cloud Sequences
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Consistent segmentation is to the center of many applications based on dynamic geometric data. Directly segmenting a raw 3D point cloud sequence is a challenging task due to the low data quality and large inter-frame ...
Laplacian Spectral Kernels and Distances for Geometry Processing and Shape Analysis
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
In geometry processing and shape analysis, several applications have been addressed through the properties of the spectral kernels and distances, such as commute-time, biharmonic, diffusion, and wave distances. Our survey ...
Transfinite Surface Patches Using Curved Ribbons
(The Eurographics Association, 2013)
An important problem in Computer Aided Design is to create digital representations for complex free-form objects that produce nice, predictable shapes and facilitate real-time editing in 3D. The clue to curve network-based ...
Accelerating kd-tree Searches for all k-nearest Neighbours
(The Eurographics Association, 2013)
Finding the k nearest neighbours of each point in a point cloud forms an integral part of many point-cloud processing tasks. One common approach is to build a kd-tree over the points and then iteratively query the k nearest ...
