Stereo-browsing from Calibrated Cameras
(The Eurographics Association, 2014)
Modern Structure-from-Motion (SfM) methods enable the registration of a set of cameras and the reconstruction of the corresponding sparse point cloud of the object/location depicted in the input images. Despite the quality ...
CHROMAGRAM: A Real-time Chroma Key Application for Mobile Devices
(The Eurographics Association, 2014)
Chroma Key is a special-effects technique widely used by television and motion picture industries for image composition. This technique allows users to replace sections identified by a chosen colour in a multimedia stream ...
TESTIMAGES: a Large-scale Archive for Testing Visual Devices and Basic Image Processing Algorithms
(The Eurographics Association, 2014)
We present the TESTIMAGES archive, a huge and free collection of sample images designed for analysis and quality assessment of different kinds of displays (i.e. monitors, televisions and digital cinema projectors) and image ...
Improving Depth Estimation Using Superpixels
(The Eurographics Association, 2014)
This work is focused on assigning a depth label to each pixel in the image. We consider off-the-shelf algorithms that provide depth information from multiple views or depth information directly obtained from RGB-d sensors. ...
GPU Visualization and Voxelization of Yarn-Level Cloth
(The Eurographics Association, 2014)
Most popular methods in cloth rendering rely on volumetric data in order to model complex optical phenomena such as sub-surface scattering. Previous work represents yarns as a sequence of identical but rotated crosssections. ...
Low Cost Recovery of Spectral Power Distributions
(The Eurographics Association, 2014)
Measuring the spectral power distribution of a light source, that is, the emission as a function of wavelength, typically requires the use of spectrophotometers or multispectral cameras. Here, we propose a low-cost system ...
CLIKSA - An Application for Physics Education in Secondary School
(The Eurographics Association, 2014)
In this paper we present an application for teaching Physics courses in secondary education. It is a web application, based on HTML5 and on JavaScript. We rely on the graphical capabilities of this technology, including ...
CAVAST: The Crows Animation, Visualization, and Simulation Testbed
(The Eurographics Association, 2014)
Simulation, animation and rendering of crowds has become an important part of real-time applications such as videogames. Virtual environments achieve higher realism when being populated by virtual crowds as opposed to ...
Adaptive Semantics Visualization
(2014-11-27)
Human access to the increasing amount of information and data plays an essential role for the professional level and also for everyday life. While information visualization has developed new and remarkable ways for visualizing ...
Controlled Metamorphosis Between Skeleton‐Driven Animated Polyhedral Meshes of Arbitrary Topologies
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Enabling animators to smoothly transform between animated meshes of differing topologies is a long‐standing problem in geometric modelling and computer animation. In this paper, we propose a new hybrid approach built upon ...
