Composition of Texture Atlases for 3D Mesh Multi-texturing
(The Eurographics Association, 2010)We introduce an automatic technique for mapping onto a 3D triangle mesh, approximating the shape of a real 3D object, a high resolution texture synthesized from several pictures taken simultaneously by real cameras surrounding ... -
Developing a Web 3.0 E-learning Portal with X3D Technologies
(The Eurographics Association, 2010)The paper describes our experience in the development of the DIEL learning management system, and especially its 3D interface, which has been developed using X3D. DIEL allows to structure learning activities along a virtual ... -
A Dimension-Independent and Extensible Framework for Huge Geometric Models
(The Eurographics Association, 2010)Nowadays, gigantic models can be easily produced in many applications and their dimension often exceeds the RAM size in a common workstation. Thus, using an external memory technique is mandatory in this case. In this ... -
Edge Adaptive and Energy Preserving Volume Upscaling for High Quality Volume Rendering
(The Eurographics Association, 2010)We describe an edge-directed optimization-based method for volumetric data supersampling. The method is based on voxel splitting and iterative refinement performed with a greedy optimization driven by the smoothing of ... -
Facile: a System for Artificial Face Dataset Generation
(The Eurographics Association, 2010)We present Facile, a system for the generation of artificial face datasets aimed to assist the training and evaluation phases of face related algorithms. Facile is able to generate, starting from a set of textured 3D faces ... -
A Framework for Virtual Restoration of Ancient Documents by Combination of Multispectral and 3D Imaging
(The Eurographics Association, 2010)Historical documents often undergo various changes over time, that alter their original state and reduce their legibility. Digital techniques are widely applied for document preservation, archiving, analysis and dissemination ... -
Improving 2D-3D Registration by Mutual Information using Gradient Maps
(The Eurographics Association, 2010)In this paper we propose an extension for the algorithms of image-to-geometry registration by Mutual Information( MI) to improve the performance and the quality of the alignment. Proposed for the registration of multi modal ... -
Manual Segmentation and Semantic-based Hierarchical Tagging of 3D models
(The Eurographics Association, 2010)Today 3D objects have become widely available in different application domains, thus it is becoming fundamental to use, integrate and develop techniques for extracting and maintaining their implicit knowledge. These ... -
Mixed Reality and Gesture Based Interaction for Medical Imaging Applications
(The Eurographics Association, 2010)This paper presents a framework providing a collection of techniques to enhance reliability, accuracy and overall effectiveness of gesture-based interaction applied to the manipulation of virtual objects within a Mixed ... -
Modeling Liquidus Hypersurfaces through Simplicial Complexes
(The Eurographics Association, 2010)This paper describes an operational pipeline that exploits computational geometry to derive useful knowledge about the crystallization behaviour of materials composed of varying amounts of pure components. Starting from ... -
Monitor-Based tracking system for Wide Augmented Reality Environments
(The Eurographics Association, 2010)In Augmented Reality (AR) applications, the technological solutions used for tracking objects in the real environment are generally related to the conditions of the environment and to the application purposes. The selection ... -
Mutual Correspondences: An Hybrid Method for Image-to-geometry Registration
(The Eurographics Association, 2010)Image registration is an important task in several applications of Computer Graphics and Computer Vision. Among the large number of proposed approaches, currently there is no solution which is automatic and robust enough ... -
Natural Interaction and Computer Graphics Applications
(The Eurographics Association, 2010)Natural Interaction with computers has been a challenging topic of research since the very beginning of the digital era and refers to the possibility, on the user s part, of exploiting natural abilities to control the ... -
Tools and Applications for Teaching and Research in Computer Graphics
(The Eurographics Association, 2010)In this paper we present the work in progress along with some preliminary research results in the field of Computational Geometry and Mesh Processing obtained by the Computer Graphics Group of the University of Cagliari, ... -
Toward Wide-Area Camera Localization for Mixed Reality
(The Eurographics Association, 2010)This paper describes a work in progress towards the implementation of a complete system that provides tourists with relevant visual information related to cultural heritage sites. Thanks to the diffusion of high-end mobile ... -
Towards a Voting Scheme for Calculating Light Source Positions from a given Target Illumination
(The Eurographics Association, 2010)Lighting conditions can make the difference between success or failure of an architectural space. The vision of space-light co-design is that architects can control the impression of an illuminated space already at an early ... -
Two Examples of GPGPU Acceleration of Memory-intensive Algorithms
(The Eurographics Association, 2010)The advent of GPGPU technologies has allowed for sensible speed-ups in many high-dimension, memory-intensive computational problems. In this paper we demonstrate the e ectiveness of such techniques by describing two ...
