Can Bi-cubic Surfaces be Class A?
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Class A surface' is a term in the automotive design industry, describing spline surfaces with aesthetic, non- oscillating highlight lines. Tensor-product B-splines of degree bi-3 (bicubic) are routinely used to generate ... -
Cell Lineage Visualisation
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Cell lineages describe the developmental history of cell populations and are produced by combining time-lapse imaging and image processing. Biomedical researchers study cell lineages to understand fundamental processes ... -
CHC+RT: Coherent Hierarchical Culling for Ray Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We propose a new technique for in-core and out-of-core GPU ray tracing using a generalization of hierarchical occlusion culling in the style of the CHC++ method. Our method exploits the rasterization pipeline and hardware ... -
Collective Crowd Formation Transform with Mutual Information–Based Runtime Feedback
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)This paper introduces a new crowd formation transform approach to achieve visually pleasing group formation transition and control. Its core idea is to transform crowd formation shapes with a least effort pair assignment ... -
Color Sequence Preserving Decolorization
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Many visualization techniques use images containing meaningful color sequences. If such images are converted to grayscale, the sequence is often distorted, compromising the information in the image.We preserve the significance ... -
Composition-Aware Scene Optimization for Product Images
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Increasingly, companies are creating product advertisements and catalog images using computer renderings of 3D scenes. A common goal for these companies is to create aesthetically appealing compositions that highlight ... -
Comprehensible Video Thumbnails
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present the Comprehensible Video Thumbnail; an automatically generated visual précis that summarizes salient objects and their dynamics within a video clip. Salient moving objects are detected within clips using a novel ... -
Compressive Image Reconstruction in Reduced Union of Subspaces
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a new compressed sensing framework for reconstruction of incomplete and possibly noisy images and their higher dimensional variants, e.g. animations and light-fields. The algorithm relies on a learning-based ... -
Compressive Volume Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Compressive rendering refers to the process of reconstructing a full image from a small subset of the rendered pixels, thereby expediting the rendering task. In this paper, we empirically investigate three image order ... -
Computing Minimum Area Homologies
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)Calculating and categorizing the similarity of curves is a fundamental problem which has generated much recent interest. However, to date there are no implementations of these algorithms for curves on surfaces with provable ... -
Consistent Scene Editing by Progressive Difference Images
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Even though much research was dedicated to the acceleration of consistent, progressive light transport simulations, the computation of fully converged images is still very time-consuming. This is problematic, as for the ... -
Content-Independent Multi-Spectral Display Using Superimposed Projections
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Many works focus on multi-spectral capture and analysis, but multi-spectral display still remains a challenge. Most prior works on multi-primary displays use ad-hoc narrow band primaries that assure a larger color gamut, ... -
Continuous Matching via Vector Field Flow
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a new method for non-rigid shape matching designed to enforce continuity of the resulting correspondence. Our method is based on the recently proposed functional map representation, which allows efficient ... -
Contrast-Enhanced Black and White Images
(The Eurographics Association and John Wiley & Sons Ltd., 2015)This paper investigates contrast enhancement as an approach to tone reduction, aiming to convert a photograph to black and white. Using a filter-based approach to strengthen contrast, we avoid making a hard decision about ... -
Controller Design for Multi‐Skilled Bipedal Characters
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)Developing motions for simulated humanoids remains a challenging problem. While there exists a multitude of approaches, few of these are reimplemented or reused by others. The predominant focus of papers in the area remains ... -
Convolution Filtering of Continuous Signed Distance Fields for Polygonal Meshes
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)Signed distance fields obtained from polygonal meshes are commonly used in various applications. However, they can have discontinuities causing creases to appear when applying operations such as blending or metamorphosis. ... -
CPH: A Compact Representation for Hierarchical Meshes Generated by Primal Refinement
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)We present CPH (): a compact representation of the hierarchical connectivity of surface and volume manifold meshes generated through primal subdivision refinements. CPH is consistently defined in several dimensions and ... -
A Cut-Cell Geometric Multigrid Poisson Solver for Fluid Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a novel multigrid scheme based on a cut-cell formulation on regular staggered grids which generates compatible systems of linear equations on all levels of the multigrid hierarchy. This geometrically motivated ... -
Data-driven Evaluation of Visual Quality Measures
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Visual quality measures seek to algorithmically imitate human judgments of patterns such as class separability, correlation, or outliers. In this paper, we propose a novel data-driven framework for evaluating such measures. ... -
Data-driven Handwriting Synthesis in a Conjoined Manner
(The Eurographics Association and John Wiley & Sons Ltd., 2015)A person's handwriting appears differently within a typical range of variations, and the shapes of handwriting characters also show complex interaction with their nearby neighbors. This makes automatic synthesis of handwriting ...
