This paper describes Just-In-Time Pixels, a technique for generating computer graphic images which are consistent with the sequential nature of common display devices. Motivation for Just-InTime Pixels is given in terms of an analysis of the sampling errors which will occur if the temporal characteristics of the raster scanned display are ignored. Included in the paper is a discussion of Just-I...

We propose a computational ghost imaging (CGI) scheme using customized pink noise speckle pattern illumination. By modulating the power spectrum distribution of speckles, we generate patterns with significant positive spatial intensity fluctuation correlation. experimentally reconstruct images our synthesized in presence variety sources and distortion show it is robust to environment. The resul...

The physical validation of computer-generated images (CGIs) has received a lot of attention from the computer graphics community, as opposed to the assessment of these images’ psychovisual quality. The field indeed lacks the proper tools to quantify the perceptual quality of a CGI; this paper engages in the construction of such a metric. A psychovisual experiment was submitted to a representati...

Anatomical Atlases are an integral part of basic health sciences education. Recently, there has been an increased importance of sectional anatomy atlases due to the advancements of tomographic and to the difficulties to relate topographic anatomy to the tridimensional anatomy. Computer-based atlases have been increasingly useful for this purpose. Delivery via the Internet and World Wide Web has...

Introduction The growth of the Internet, the diffusion of access to technology, and boosts in bandwidth, have facilitated people's ability to increasingly use telecommunication technologies to create and maintain both business and social Kiesler, & McGuier, 1986). More people are using the environments to maintain a broader range of social relationships. People have not only responded socially ...

Traditionally, computer science curricula have focused on the algorithmic development of software, while design issues such as typography, text layout, and image manipulation have been the domain of graphic design or fine arts programs. With the emergence of the Web as a publishing and programming medium, as well as the availability of high-level development tools, the distinctions between algo...

Virtual Reality is the research framework of computer science, which is adressed by this thesis. Motivated by an application related goal of Computer Aided Styling, the simulation of surfaces by computer graphic textures is evaluated. Computer graphic textures and their placement are well known and accepted techniques to implement interactive Virtual Reality simulations. This thesis aims at the...

Cattle supply an important source of nutrition for humans in the world. CpG islands (CGIs) are very important and useful, as they carry functionally relevant epigenetic loci for whole genome studies. As a matter of fact, there have been no formal analyses of CGIs at the DNA sequence level in cattle genomes and therefore this study was carried out to fill the gap. We used hidden markov model alg...
