Digitized books and manuscripts in digital libraries are often stored as images or graphics. They are not searchable at the content level due to the lack of OCRs or poor quality of the scanned images. Portable Document Format (PDF) has emerged as the most popular document representation schema for wider access across platforms. When there is no textual (UNICODE, ASCII) representation available,...

The emergence and continuing use of multi-core architectures and graphics processing units require changes in the existing software and sometimes even a redesign of the established algorithms in order to take advantage of now prevailing parallelism. Parallel Linear Algebra for Scalable Multi-core Architectures (PLASMA) and Matrix Algebra on GPU and Multics Architectures (MAGMA ) are two project...

In the context of Web 2.0, text content is often heterogenous (i.e. lexical heterogeneity). For instance, some words may be shortened or lengthened with the use of specific graphics (e.g. emoticons) or hashtags. Specific processing is necessary in this context. For instance, with an opinion classification task based on the message SimBig is an aaaaattractive conference!, the results are general...

www.poynton.com [email protected] This FAQ is intended to clarify aspects of color that are important to color image coding, computer graphics, image processing, video, and the transfer of digital images to print. I assume that you are familiar with intensity, luminance (CIE Y), lightness (CIE L*), and the nonlinear relationship between CRT voltage and intensity (gamma). To learn more about t...

As a result of the demand for high performance graphics capabilities driven by the computer video game industry, the processing performance of video cards is rapidly evolving. Recent trends in computing have shifted toward multi-core processors and programmable graphics processors equipped with highly parallel data paths for processing geometry and pixels. Multi-core machines are now readily av...

0. Abstract This paper outlines the general use of the GPU interface defined in shader languages, for the design of large-scale effects with per-pixel clarity. At this point, the stability of GPU programming has matured, and effects can be used reliably on most consumer hardware. Coupled with the low efficiency reduction and short code segments, the incorporation of shader effects seems to have...

The Probability Density Function (PDF) is a key concept in statistics. Constructing the most adequate PDF from the observed data is still an important and interesting scientific problem, especially for large datasets. PDFs are often estimated using nonparametric data-driven methods. One of the most popular nonparametric method is the Kernel Density Estimator (KDE). However, a very serious drawb...

This paper outlines some of the complex relationships between the curriculum and technology, with particular attention on graphics calculators. Graphics calculators are of key significance for practical reasons of availability and affordability Until technology is available, curricula are not likely to be adjusted to accommodate them. Particular features of graphics calculators, including their...
