Theory and Methods of Light-Field Photography
(The Eurographics Association, 2008)
Computational photography is based on capturing and processing discrete representations of all the light rays in the 3D space. Compared to conventional photography, which captures 2D images, computational photography ...
Graphics based Computer Adaptive Testing and Beyond
(The Eurographics Association, 2008)
Instead of computer games, animations, cartoons, and videos being used only for entertainment by kids, there is now an interest in using graphics for 'innovative testing'. Rather than traditional pen-and-paper tests, audio, ...
A Fragile Watermarking Scheme for Authentication of Semi-regular Meshes
(The Eurographics Association, 2008)
This paper presents a fragile watermarking scheme for authentication of 3D semi-regular meshes. After one wavelet decomposition, the watermark is inserted by slightly modifying the norms and orientations of the obtained ...
From a Light CG Framework to a strong Cannibal Experience
(The Eurographics Association, 2008)
Game development courses are being more and more deployed within computer graphics (CG) curricula. A fundamental element in the pedagogical effectiveness of such courses is the quality of the development framework provided ...
The Beam Radiance Estimate for Volumetric Photon Mapping
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
We present a new method for efficiently simulating the scattering of light within participating media. Using a theoretical reformulation of volumetric photon mapping, we develop a novel photon gathering technique for ...
What Can We Gain from Transdisciplinary Visualization Courses?
(The Eurographics Association, 2008)
Transdisciplinary education means going even further in the collaboration with other disciplines than multidisciplinary and interdisciplinary education do. Transdisciplinary education attempts to search for new insights ...
Sparse points matching by combining 3D mesh saliency with statistical descriptors
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
This paper proposes new methodology for the detection and matching of salient points over several views of an object. The process is composed by three main phases. In the first step, detection is carried out by adopting a ...
