Fractal descriptors in the Fourier domain applied to color texture analysis
(American Institute of Physics - AIPCollege Park, 2011-12)
The present work proposes the development of a novel method to provide descriptors for colored texture images. The method consists of two steps. First, we apply a linear transform in the color space of the image aiming at ...
Fourier homogenization method and the propagation of acoustic waves through a periodic vortex array
The classical problem of homogenization of elliptic operators in arbitrary domains with periodically oscillating coe cients is considered. As the period goes to zero, an asymptotic analysis of the corresponding sequence ...
Fractal descriptors based on Fourier spectrum applied to texture analysis
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
This work proposes the development and study of a novel technique lot the generation of fractal descriptors used in texture analysis. The novel descriptors are obtained from a multiscale transform applied to the Fourier ...
An exact series solution for the vibration analysis of cylindrical shells with arbitrary boundary conditions
In this paper, an exact series solution for the vibration analysis of circular cylindrical shells with arbitrary boundary conditions is obtained, using the elastic equations based on Flügge's theory. Each of the three ...
