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 ... -
Database-Assisted Object Retrieval for Real-Time 3D Reconstruction
(The Eurographics Association and John Wiley & Sons Ltd., 2015)In recent years, real-time 3D scanning technology has developed significantly and is now able to capture large environments with considerable accuracy. Unfortunately, the reconstructed geometry still suffers from incompleteness, ... -
Data‐Driven Automatic Cropping Using Semantic Composition Search
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a data‐driven method for automatically cropping photographs to be well‐composed and aesthetically pleasing. Our method matches the composition of an amateur's photograph to an expert's using point correspondences. ... -
Deformable Objects Collision Handling with Fast Convergence
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a stable and efficient simulator for deformable objects with collisions and contacts. For stability, an optimization derived from the implicit time integrator is solved in each timestep under the inequality ... -
DenseCut: Densely Connected CRFs for Realtime GrabCut
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Figure-ground segmentation from bounding box input, provided either automatically or manually, has been extremely popular in the last decade and influenced various applications. A lot of research has focused on highquality ... -
Designing Camera Networks by Convex Quadratic Programming
(The Eurographics Association and John Wiley & Sons Ltd., 2015)In this paper, we study the problem of automatic camera placement for computer graphics and computer vision applications. We extend the problem formulations of previous work by proposing a novel way to incorporate visibility ... -
Detangler: Visual Analytics for Multiplex Networks
(The Eurographics Association and John Wiley & Sons Ltd., 2015)A multiplex network has links of different types, allowing it to express many overlapping types of relationships. A core task in network analysis is to evaluate and understand group cohesion; that is, to explain why groups ...
