چکیده

Visual scalability is the capability of visualization tools effectively to display large data sets, in terms of either the number or the dimension of individual data elements. In this paper, we define and structure the problem of visual scalability, with special emphasis on the role of visualization as a means of access to details of the data. This is done abstractly in terms of responses that measure the business or scientific impact of visualizations and factors that affect the responses, and concretely in terms of measures of visual scalability and factors influencing them. We assess both current capabilities and future prospects along a number of dimensions. Our approach for increasing visual scalability includes improved visual metaphors, interactivity and perspectives that link multiple views. ∗Research supported in part by NSF grants SBE–9529926 and EIA–9876619 to the National Institute of Statistical Sciences.

A visual SOA-based ontology alignment tool

Ontology alignment is the process of matching related concepts from different ontologies. We propose a semi-automatic, visual approach which combines two algorithms for finding candidate alignments with visual navigation and analysis tools. The implementation is based on a ServiceOriented Architecture (SOA) to achieve scalability.

Point-Wise Extended Visual Masking for JPEG-2000 Image Compression

One common visual optimization strategy for image compression is to exploit the visual masking effect where artifacts are locally masked by the image acting as a background signal. In this paper, we present a point-wise extended visual masking approach that nonlinearly maps the wavelet coefficients to a perceptually uniform domain prior to quantization by taking advantages of both selfcontrast ...
