An Introductory Course on Visualization: a proposal
Beatriz Sousa SantosA Visualization course designed to be offered as an elective in the MSc degree on Electronics and Telecommunications at the University of Aveiro is proposed. Its curriculum and bibliography are presented. ; Apresenta-se uma proposta para o curriculum de uma disciplina de Visualização a oferecer ao Mestrado em Electrónica e Telecomunicações da Universi...
Evaluation of Volume Visualizations: Proposal of a Tool
Beatriz Sousa SantosSome issues relevant to the design of a tool for the evaluation of volume visualizations are presented, as well as a proposal for its general functionality. This tool should offer the user, among others, the possibility of importing and exporting real or synthetic test data, generating synthetic data with controlled parameters, using several volume visualization techniques and appl...
Assessing the Quality of Visualizations Produced Using Volume Rendering: Experi...
Beatriz Sousa Santos; José Nunes; Carlos Coimbra; Carlos Ferreira; Ana Maria Tomé; Nuno LauA set of parameters to assess the objective quality of visualizations of a voxel based data set, produced using a ray caster, is proposed as a first step toward the evaluation of the overall quality of these visualizations.Results obtained using synthetic data and a simple implementation of a ray caster are presented. The final goal of this evaluation will be the computation of “c...
The Human Visual System in Electronics Engineering Education
Beatriz Sousa SantosUnderstanding the Human Visual System is fundamental in certain areas as Digital Image Processing, Computer Graphics, Visualization and Human Computer Interaction, where methods and systems are designed to produce images meant to be viewed by humans. A brief description of the way such a topic is addressed in several elective courses of the last year of the Electronics Enginee...
Interface de Utilizador para um Sistema de Monitorização e Gestão da Produção d...
Paulo Marrafa; Beatriz Sousa SantosA system for monitoring and managing the production of a label manufacture using the well known MÜLLER label weaving machines (jaquard machines) is proposed. The user interface of this system developed for Windows platforms is also described. ; Neste artigo propõe-se um sistema para monitorização e gestão da produção de uma tecelagem de&nb...
Some Recurrent Concepts of Quality Evaluation in Medical Visualization
Beatriz Sousa Santos; Jean Louis Dillenseger; Jean Louis CoatrieuxSome concepts that seem fundamental for the quality evaluation of data visualization in general and of medical data in particular are presented. ; Apresentam-se neste trabalho alguns conceitos que parecem fundamentais no problema da avaliação da qualidade da visualização em geral e de dados médicos em particular.
Exploração Virtual de uma embarcação do sec. XV afundada na ria de Aveiro
João Manuel Tavares; Beatriz Sousa Santos; Joaquim Sousa PintoThis paper present a prototype of an Application to visualize data from pottery found in a XVth century shipwreck in the Aveiro lagoon.This application was developed in VRML 2.0 and allows the tridimensional exploration of the relative position of thedifferent pottery pieces as well as the access to some other information concerning each piece of pottery. ; Este artigo apresenta um prot&oac...
Design and Implementation of a Hardware Coprocessor for Ray Caster Volume Rende...
Arnaldo Oliveira; Beatriz Sousa SantosThis paper discusses the implementation of an hardware coprocessor for volume rendering. This type of applications requires much storage and computational resources. However, high performance processing isn’t easily achieved without dedicated hardware. The proposed approach takes full advantage of reconfigurable hardware, which allows sharing the same hardware among different...
Software Application for Data Visualization and Interaction in a Location Routi...
Andreia Melo; Beatriz Sousa Santos; Carlos Ferreira; Joaquim Sousa PintoThis paper describes an application developed for Windows platforms, which is meant to be used for inputting data and visualizing results of a Location-Routing problem of obnoxious services and materials. The main goal of this application is to provide, through a “usable” user interface, an intuitive of inputting the information needed to solve the problem as well as to...
Ray Casting: Uma implementação com vista à realização de estudos de qualidade
Paulo Breda Vieira; Beatriz Sousa SantosAn application to visualize voxel based volumes using a ray-caster is presented. This application is meant to allow studing the quality of obtained visualizations and thus the values of a set of parameters relevant to the final quality may be selected. ; Neste artigo apresenta-se uma aplicação desenvolvida para possibilitar a visualização de volumes def...
