ExplorerTree: a focus+context exploration approach for 2D embeddings
Wilson E. Marcílio-Jr, Danilo M. Eler, Fernando V. Paulovich +2
In exploratory tasks involving high-dimensional datasets, dimensionality reduction (DR) techniques help analysts to discover patterns and other useful information. Although scatter…
Techniques for effective and efficient fire detection from social media images
Marcos Bedo, Gustavo Blanco, Willian Oliveira +5
Social media could provide valuable information to support decision making in crisis management, such as in accidents, explosions and fires. However, much of the data from social m…
Combining Visual Analytics and Content Based Data Retrieval Technology for Efficient Data Analysis
Jose Rodrigues, Luciana Romani, Agma Traina +1
One of the most useful techniques to help visual data analysis systems is interactive filtering (brushing). However, visualization techniques often suffer from overlap of graphical…
A Survey on Distributed Visualization Techniques over Clusters of Personal Computers
Jose Rodrigues, Andre Balan, Luciana Zaina +1
In the last years, Distributed Visualization over Personal Computer (PC) clusters has become important for research and industrial communities. They have made large-scale visualiza…
GMine: A System for Scalable, Interactive Graph Visualization and Mining
Jose Rodrigues, Hanghang Tong, Agma Traina +2
Several graph visualization tools exist. However, they are not able to handle large graphs, and/or they do not allow interaction. We are interested on large graphs, with hundreds o…
BoWFire: Detection of Fire in Still Images by Integrating Pixel Color and Texture Analysis
Daniel Y. T. Chino, Letricia P. S. Avalhais, Jose F. Rodrigues +1
Emergency events involving fire are potentially harmful, demanding a fast and precise decision making. The use of crowdsourcing image and videos on crisis management systems can ai…
Reviewing Data Visualization: an Analytical Taxonomical Study
Jose F. Rodrigues, Agma J. M. Traina, Maria Cristina F. de Oliveira +1
This paper presents an analytical taxonomy that can suitably describe, rather than simply classify, techniques for data presentation. Unlike previous works, we do not consider part…
StructMatrix: large-scale visualization of graphs by means of structure detection and dense matrices
Hugo Gualdron, Robson Cordeiro, Jose Rodrigues
Given a large-scale graph with millions of nodes and edges, how to reveal macro patterns of interest, like cliques, bi-partite cores, stars, and chains? Furthermore, how to visuali…
M-Flash: Fast Billion-scale Graph Computation Using a Bimodal Block Processing Model
Hugo Gualdron, Robson Cordeiro, Jose Rodrigues-Jr +3
Recent graph computation approaches have demonstrated that a single PC can perform efficiently on billion-scale graphs. While these approaches achieve scalability by optimizing I/O…
The Spatial-Perceptual Design Space: a new comprehension for Data Visualization
Jose F. Rodrigues, Agma J. M. Traina, Maria C. F. Oliveira +1
We revisit the design space of visualizations aiming at identifying and relating its components. In this sense, we establish a model to examine the process through which visualizat…
Large Graph Analysis in the GMine System
Jose F. Rodrigues, Hanghang Tong, Jia-Yu Pan +3
Current applications have produced graphs on the order of hundreds of thousands of nodes and millions of edges. To take advantage of such graphs, one must be able to find patterns,…
A survey on Information Visualization in light of Vision and Cognitive sciences
Jose Rodrigues-Jr, Luciana Zaina, Maria Oliveira +2
Information Visualization techniques are built on a context with many factors related to both vision and cognition, making it difficult to draw a clear picture of how data visually…
