On the Representation of Visual Information
2001Loss of information in images undergoing fine-to-coarse image transformations is analized by using an approach based on the theory of irreversible transformations. It is shown that entropy variation along scales can be used to characterize basic, low-level information and to gauge essential perceptual components of the image, such as shape and texture.

Evolving visual representations
ACM SIGGRAPH 2006 Research posters on - SIGGRAPH '06, 2006A number of evolutionary systems exist that allow the generation of esthetically pleasing images and animation. Most of these systems rely on "user-centric" fitness functions based on interactive selection. Although interactive selection is a useful tool that allows for subjective fitness evaluation, it is also restrictive as it works with a small ...

Visual representations for recursion
International Journal of Human-Computer Studies, 2001Summary: Visualcode is a visual notation that uses coloured expressions and graphical environments to describe the execution of Scheme programs. RainbowScheme is a program visualization system which is designed to produce visualcode representations of step-by-step execution of Scheme programs.

We depict the weight diagrams (alias, crystal graphs) of basic and adjoint representations of complex simple Lie algebras/algebraic groups and describe some of their uses.

Visual Representation of Reifications in RDF Visualizer
2009 13th International Conference Information Visualisation, 2009One family of visualization tools for the Semantic web are those that directly display the underlying RDF data. Most of them use the inherent graph structure of RDF data and present the user with some drawing of the graph. While it is usually sufficient to give the user with decent understanding of data, there are some features of RDF that could be ...

The representation of visual scenes
Trends in Cognitive Sciences, 1997The visual world exists all around us, yet this information must be gleaned through a succession of eye fixations in which high visual acuity is limited to the small foveal region of each retina. In spite of these physiological constraints, we experience a richly detailed and continuous visual world.

1994
Schemes to compact spatial data into representations that facilitate the computation of geometrical properties and favor shape description are discussed in this paper. Any region, resulting after image segmentation, can be basically represented in terms of its external characteristics (the contour of the region), or of its internal characteristics (the

3D representations for software visualization
Proceedings of the 2003 ACM symposium on Software visualization, 2003The paper presents a new 3D representation for visualizing large software systems. The origins of this representation can be directly traced to the SeeSoft metaphor. This work extends these visualization mechanisms by utilizing the third dimension, texture, abstraction mechanism, and by supporting new manipulation techniques and user interfaces.

Cooperative Representation of Visual Borders
Perception, 1992Recently it has been reported that the visual cortical cells which are engaged in cooperative coding of global stimulus features, display synchrony in their firing rates when both are stimulated. Alternative models identify global stimulus features with the coarse spatial scales of the image.
