Extraction of Dominant Extremal Structures in Volumetric Data Using Separatrix Persistence
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Extremal lines and surfaces are features of a 3D scalar field where the scalar function becomes minimal or maximal with respect to a local neighborhood
Smart Scribbles for Sketch Segmentation
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
We present ‘Smart Scribbles’—a new scribble‐based interface for user‐guided segmentation of digital sketchy drawings. In contrast to previous approaches based on simple selection strategies, Smart Scribbles exploits richer ...
Temporal Blending for Adaptive SPH
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
In this paper, we introduce a fast and consistent smoothed particle hydrodynamics (SPH) technique which is suitable for convection–diffusion simulations of incompressible fluids. We apply our temporal blending technique ...
Comparison of Four Subjective Methods for Image Quality Assessment
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
To provide a convincing proof that a new method is better than the state of the art, computer graphics projects are often accompanied by user studies, in which a group of observers rank or rate results of several algorithms. ...
Data‐Parallel Decompression of Triangle Mesh Topology
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
We propose a lossless, single‐rate triangle mesh topology codec tailored for fast data‐parallel GPU decompression. Our compression scheme coherently orders generalized triangle strips in memory. To unpack generalized ...
Content‐Aware Automatic Photo Enhancement
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Automatic photo enhancement is one of the long‐standing goals in image processing and computational photography. While a variety of methods have been proposed for manipulating tone and colour, most automatic methods used ...
Dependency‐Free Parallel Progressive Meshes
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
The constantly increasing complexity of polygonal models in interactive applications poses two major problems. First, the number of primitives that can be rendered at real‐time frame rates is currently limited to a few ...
CageR: Cage‐Based Reverse Engineering of Animated 3D Shapes
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
We present CageR: A novel framework for converting animated 3D shape sequences into compact and stable cage‐based representations. Given a raw animated sequence with one‐to‐one point correspondences together with an initial ...
Linear Surface Reconstruction from Discrete Fundamental Forms on Triangle Meshes
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
We present a linear algorithm to reconstruct the vertex coordinates for a surface mesh given its edge lengths and dihedral angles, unique up to rotation and translation. A local integrability condition for the existence ...
Biharmonic Coordinates
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Barycentric coordinates are an established mathematical tool in computer graphics and geometry processing, providing a convenient way of interpolating scalar or vector data from the boundary of a planar domain to its ...
