A VISUALIZATION METHOD BASED ON FOVEATION
Arzu Çöltekin · 2005
A human visual system inspired process called foveation is an approach in managing the level of detail by controlling the region of interest. The scene is segmented according to the principles of our visual perception, modeling how the fovea behaves. Foveation is interesting for designing robot eyes, and in bandwidth/resource hungry visualization tasks. It is also relevant for limited hardware capacity and processing very large datasets. Photogrammetry, Remote Sensing and Cartography deals with large images and scenes. Even though there are a few different approaches for managing the level of detail; foveation is not widely known or utilized in these fields. This paper presents an introduction to foveation, an argumentation of how and why it could be useful for Geoinformation applications. An implementation of foveation for stereo imaging, called Foveaglyph, is also presented to demonstrate the concept.
