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 ...
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 ...
Adaptive Quad Mesh Simplification
(The Eurographics Association, 2010)
We present an improved algorithm for the progressive simplification of quad meshes, which adapts the resolution of the mesh to details of the modeled shape. We extend previous work [TPC*10], by simplifying the approach and ...
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, ...
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 ...
Building Morphological Representations for 2D and 3D Scalar Fields
(The Eurographics Association, 2010)
Ascending and descending Morse complexes, defined by the critical points and integral lines of a scalar field f defined on a manifold domain D, induce a subdivision of D into regions of uniform gradient flow, and thus ...
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 ...
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 ...
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 ...
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 ...
