3D Material Style Transfer
(The Eurographics Association and John Wiley and Sons Ltd., 2012)This work proposes a technique to transfer the material style or mood from a guide source such as an image or video onto a target 3D scene. It formulates the problem as a combinatorial optimization of assigning discrete ... -
Adaptation of Electrical Laboratory Systems through Augmented Reality for Optimization of Engineering Teaching University
(The Eurographics Association, 2012)This paper introduces an Augmented Reality (AR) application for teaching practices of electrical engineering. In order to improve the autonomy of students and their self-ability we have developed several new practical ... -
Advected Tangent Curves: A General Scheme for Characteristic Curves of Flow Fields
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We present the first general scheme to describe all four types of characteristic curves of flow fields - stream, path, streak, and time lines - as tangent curves of a derived vector field. Thus, all these lines can be ... -
Analytic Anti-Aliasing of Linear Functions on Polytopes
(The Eurographics Association and John Wiley and Sons Ltd., 2012)This paper presents an analytic formulation for anti-aliased sampling of 2D polygons and 3D polyhedra. Our framework allows the exact evaluation of the convolution integral with a linear function defined on the polytopes. ... -
Automatic Alignment of Shape Collections
(The Eurographics Association, 2012)We present a method for automatically aligning a collection of similar shapes in arbitrary initial poses. By analyzing the shape collection we extract a deformation model to capture the variability in the collection. We ... -
Automatic Line Handles for Freeform Deformation
(The Eurographics Association, 2012)Interactive freeform surface deformation methods allow to explore the space of possible shapes using simple control structures. While recent advances in variational editing provide high quality deformations, designing ... -
Automatic Multi-view Surface Matching
(The Eurographics Association, 2012)In this paper we tackle the problem of automatically aligning an unordered set of range views. We propose a full pipeline that goes from the scans to the complete 3D model. The emphasis is on the automation no manual ... -
Automatically Rigging Multi-component Characters
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Rigging an arbitrary 3D character by creating an animation skeleton is a time-consuming process even for experienced animators. In this paper, we present an algorithm that automatically creates animation rigs for multicomponent ... -
Black is Green: Adaptive Color Transformation For Reduced Ink Usage
(The Eurographics Association and John Wiley and Sons Ltd., 2012)A vast majority of color transformations applied to an image in the digital press industry are static and precalculated. In order to achieve the best quality on a wide variety of different images, these transformations ... -
Building a Serious Game to Teach Secure Coding in Introductory Programming Courses
(The Eurographics Association, 2012)We report the development and initial evaluation of a serious game that, in conjunction with appropriately designed matching laboratory exercises, can be used to teach secure coding and Information Assurance (IA) concepts ... -
A Cell-Based Light Interaction Model for Human Blood
(The Eurographics Association and John Wiley and Sons Ltd., 2012)The development of predictive appearance models for organic tissues is a challenging task due to the inherent complexity of these materials. In this paper, we closely examine the biophysical processes responsible for the ... -
Centroidal Voronoi Tessellation of Line Segments and Graphs
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Centroidal Voronoi Tessellation (CVT) of points has many applications in geometry processing, including remeshing and segmentation, to name but a few. In this paper, we generalize the CVT concept to graphs via a variational ... -
Coding Depth through Mask Structure
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We present a coded-aperture method based on a family of masks obtained as the convolution of one "hole" with a structural component consisting of an arrangement of Dirac delta functions. We call the arrangement of delta ... -
Coherent Spatiotemporal Filtering, Upsampling and Rendering of RGBZ Videos
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Sophisticated video processing effects require both image and geometry information. We explore the possibility to augment a video camera with a recent infrared time-of-flight depth camera, to capture high-resolution RGB ... -
Combining Structure from Motion and Photometric Stereo: A Piecewise Formulation
(The Eurographics Association, 2012)This paper introduces a novel piecewise formulation for Photometric Stereo on static scenes exploiting a set of multiple view constraints on the surface. Such constraints will help to recover geometrical properties of the ... -
Combining Texture Streaming and Run-Time Generation
(The Eurographics Association, 2012)Virtual texturing systems have enabled gigapixel resolutions for textures used in real-time rendering. This allows for more detail and diversity in virtual worlds at the cost of greatly increasing disc storage requirements. ... -
Computational Design of Rubber Balloons
(The Eurographics Association and John Wiley and Sons Ltd., 2012)This paper presents an automatic process for fabrication-oriented design of custom-shaped rubber balloons. We cast computational balloon design as an inverse problem: given a target shape, we compute an optimal balloon ... -
A Computational Model of Afterimages
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Afterimages are optical illusions, particularly well perceived when fixating an image for an extended period of time and then looking at a neutral background, where an inverted copy of the original stimulus appears. The ... -
Consistent Media Model for Real-Time Scene Rendering
(The Eurographics Association, 2012)We present a consistent model for artistic media reproduction in 3D scene renderings and animations. Artistic media reproduction can be defined as a media model (such as brush, pencil, ink) and a support (such as canvas ... -
A Continuous, Editable Representation for Deforming Mesh Sequences with Separate Signals for Time, Pose and Shape
(The Eurographics Association and John Wiley and Sons Ltd., 2012)It is increasingly popular to represent non-rigid motion using a deforming mesh sequence: a discrete sequence of frames, each of which is given as a mesh with a common graph structure. Such sequences have the flexibility ...
