Proactive Graphics for Exploratory Visualization of Biogeographical Data

Barbara P. Buttenfield, Christopher R. Weber
1994 Cartographic Perspectives  
In addition, graphical displays may guide database query design, providing visual means to identify either logical inconsistencies or barriers to information access.  ...  In an associative environment, the receiving of information (through a successful data query, e.g.) is likely to generate a demand for further information.  ...

When music makes a scene

Cynthia C. S. Liem, Martha Larson, Alan Hanjalic
2013 International Journal of Multimedia Information Retrieval  
However, if the connotative associations between music and visual narrative are strong enough, characterizations of music in terms of a narrative multimedia context can be envisioned.  ...  A lay user who wants to use music in a similar way may have a result in mind, but may lack the right musical vocabulary to express the corresponding information need.  ...  Acknowledgments Cynthia Liem is a recipient of the Google European Doctoral Fellowship in Multimedia, and this research is supported in part by this Google Fellowship.  ...

Correlated Photon Mapping for Interactive Global Illumination of Time-Varying Volumetric Data

Daniel Jonsson, Anders Ynnerman
2017 IEEE Transactions on Visualization and Computer Graphics  
Our method uses the identification of photon traces invariant to changes of visual parameters such as the transfer function (TF), or data changes between time-steps in a 4D volume.  ...  A low resolution uniform grid containing the minimum and maximum data values of the original data is derived for each time step.  ...  INTRODUCTION Interactive visualization of volumetric data through Direct Volume Rending (DVR) is an important tool for both presentation and exploration in a wide range of domains.  ...

2009 ACM SIGMultimedia Records  
We aim at providing techniques to allow the remote walkthrough of users in a natural 3D scene ensuring botanical coherency and interactivity.  ...  First, we provide a compact and progressive representation for botanically realistic plant models. The topological structure and the geometry of the plants are represented by generalized cylinders.  ...  A loss in a video stream, even for a key-frame, may have visual consequences only for a few seconds.  ...

Logics for XML [article]

Pierre Geneves
2008 arXiv   pre-print
This thesis describes the theoretical and practical foundations of a system for the static analysis of XML processing languages.  ...  The system relies on a fixpoint temporal logic with converse, derived from the mu-calculus, where models are finite trees.  ...  The work found in [Cardelli and Ghelli, 2004] proposes the TQL logic as the core of a query language for semistructured data represented as unranked trees and unordered trees.  ...
