Methods for Analytical Understanding of Agent-Based Modeling of Complex Systems
Gilson A. Giraldi, Luis C. da Costa, Adilson V. Xavier +1
Von Neuman's work on universal machines and the hardware development have allowed the simulation of dynamical systems through a large set of interacting agents. This is a bottom-up…
Lattice Gas Cellular Automata for Computational Fluid Animation
Gilson A. Giraldi, Adilson V. Xavier, Antonio L. Apolinario +1
The past two decades showed a rapid growing of physically-based modeling of fluids for computer graphics applications. In this area, a common top down approach is to model the flui…
Convexity Analysis of Snake Models Based on Hamiltonian Formulation
Gilson Antonio Giraldi, Antonio Alberto Fernandes de Oliveira
This paper presents a convexity analysis for the dynamic snake model based on the Potential Energy functional and the Hamiltonian formulation of the classical mechanics. First we s…
Gradient Vector Flow Models for Boundary Extraction in 2D Images
Gilson A. Giraldi, Leandro S. Marturelli, Paulo S. Rodrigues
The Gradient Vector Flow (GVF) is a vector diffusion approach based on Partial Differential Equations (PDEs). This method has been applied together with snake models for boundary e…
