Visualizing hierarchical data is one of the core areas of information visualization. Most of these techniques focus on single hierarchies hierarchies with a single root element and a single path to each element. In contrast, ...

This work introduces a volume rendering technique that is conceptually based on the shear-warp factorization. We propose to perform the shear transformation in the frequency domain. Unlike the standard shear-warp algorithm, ...

In this paper we present a simple and efficient vortex core region detection algorithm based on ideas derived from combinatorial topology. These ideas originated from Sperner s lemma, which by itself is of little value to ...

The following methodological model can be used as a platform for the study of the impact of information and communications technologies (ICT) at cultural heritage sites. The model has been developed through extensive, ...

We recently proposed a multiresolution representation for maximum intensity projection (MIP) volume rendering based on morphological adjunction pyramids which allow progressive refinement and have the property of perfect ...

We present a simple and robust method for computing skeletons for arbitrary planar objects and centerlines for 3D objects. We augment the Fast Marching Method (FMM) widely used in level set applications 11 by computing the ...

We describe a novel approach to visualize bibliographic networks that facilitates the simultaneous identification of clusters (e.g., topic areas) and prominent entities (e.g., surveys or landmark papers). While employing ...

The issue addressed in this paper is at first a brief presentation of the Technical Guidelines for IPR protection and management applied to Greek cultural digitization projects. Secondly, the work focuses on the analysis ...

Iso-surface extraction is one of the most important approaches for volume rendering, and iso-contouring is one of the most effective methods for iso-surface extraction. Unlike most other methods having their search domain ...

The discipline of graph visualization produces pictorial representations of node link structures. Much effort has been directed toward making such diagrams visually pleasing. A variety of aesthetic heuristics have been ...
