Contour polygonal approximation using shortest path in networks
André Ricardo Backes, Dalcimar Casanova, Odemir Martinez Bruno
Contour polygonal approximation is a simplified representation of a contour by line segments, so that the main characteristics of the contour remain in a small number of line segme…
Predicting Efficiency in master-slave grid computing systems
Gonzalo Travieso, Carlos A. Ruggiero, Odemir M. Bruno +1
This work reports a quantitative analysis to predicting the efficiency of distributed computing running in three models of complex networks: Barabási-Albert, Erdős-Rényi and Watts-…
On the Efficiency of Data Representation on the Modeling and Characterization of Complex Networks
Carlos A. Ruggiero, Odemir M. Bruno, Gonzalo Travieso +1
Specific choices about how to represent complex networks can have a substantial effect on the execution time required for the respective construction and analysis of those structur…
An entropy-based approach to automatic image segmentation of satellite images
A. L. Barbieri, G. Arruda, F. A. Rodrigues +2
An entropy-based image segmentation approach is introduced and applied to color images obtained from Google Earth. Segmentation refers to the process of partitioning a digital imag…
