Applying Lie Groups Approaches for Rigid Registration of Point Clouds
Liliane Rodrigues de Almeida, Gilson A. Giraldi, Marcelo Bernardes Vieira
In the last decades, some literature appeared using the Lie groups theory to solve problems in computer vision. On the other hand, Lie algebraic representations of the transformati…
Is human face processing a feature- or pattern-based task? Evidence using a unified computational method driven by eye movements
Carlos E. Thomaz, Vagner Amaral, Gilson A. Giraldi +2
Research on human face processing using eye movements has provided evidence that we recognize face images successfully focusing our visual attention on a few inner facial regions,…
Fourier Analysis and q-Gaussian Functions: Analytical and Numerical Results
Paulo Sérgio Silva Rodrigues, Gilson Antonio Giraldi
It is a consensus in signal processing that the Gaussian kernel and its partial derivatives enable the development of robust algorithms for feature detection. Fourier analysis and…
Variational Time Integration Approach for Smoothed Particle Hydrodynamics Simulation of Fluids
Leandro Tavares da Silva, Gilson Antonio Giraldi
Variational time integrators are derived in the context of discrete mechanical systems. In this area, the governing equations for the motion of the mechanical system are built foll…
A Review of Dynamic NURBS Approach
Josildo Pereira da Silva, Antônio Lopes Apolinário Júnior, Gilson A. Giraldi
Dynamic NURBS, also called D-NURBS, is a known dynamic version of the nonuniform rational B-spline (NURBS) which integrates free-form shape representation and a physically-based mo…
Fourier Analysis and Holographic Representations of 1D and 2D Signals
G. A. Giraldi, B. F. Moutinho, D. M. L. de Carvalho +1
In this paper, we focus on Fourier analysis and holographic transforms for signal representation. For instance, in the case of image processing, the holographic representation has…
