Estimating crowd density with Minkowski fractal dimension
The estimation of the number of people in an area under surveillance is very important for the problem of crowd monitoring. When an area reaches an occupation level greater than the projected one, people's safety can be ...
Higuchi fractal dimension applied to RR intervals in children with Attention Deficit Hyperactivity Disorder
Background: Attention deficit hyperactivity disorder (ADHD) is categorized by a lowered attention span, recklessness, and hyperactivity. Autonomic nervous system inequality has previously been studied using the same data ...
Closed contour fractal dimension estimation by the Fourier transform
This work proposes a novel technique for the numerical calculus of the fractal dimension of fractal objects which can be represented as a closed contour. The proposed method maps the fractal contour onto a complex signal ...
Texture analysis by multi-resolution fractal descriptors
This work proposes a novel texture descriptor based on fractal theory. The method is based on the Bouligand- Minkowski descriptors. We decompose the original image recursively into four equal parts. In each recursion step, ...
Fractal analysis along stretch zone for an aluminum alloy
(Elsevier B.V., 2005-03-01)
The topography of fracture surface along stretch zone front for Al7050 is analyzed about its fractal behavior and compared against local distributions of microstructural parameters and stretch zone height, considered here ...

Aplicação do método box counting para a estimativa da dimensão fractal de figuras planas digitalizadas
(Universidade Federal de Santa MariaCentro de Ciências Rurais, 2007-12-17)
Many forms in the nature can not be explained in the molds of the conventional mathematics. In order to fulfill this need scientists have developed the fractal geometry. The science of Fractals, since its origin, is the ...
Hydrophobicity classification of polymeric materials based on fractal dimension
(ABM, ABC, ABPol, 2008)
This study proposes a new method to obtain hydrophobicity classification (HC) in high voltage polymer insulators. In the method mentioned, the HC was analyzed by fractal dimension (fd) and its processing time was evaluated ...
Temporal evolution of fractality in the Earth's magnetosphere and the solar photosphere
(Blackwell Publishing Ltd, 2014)
The study of complexity in two aspects of the magnetic activity in the Sun-Earth system is presented. We compare the temporal evolution of the magnetic fluctuations in the Earth's magnetosphere and the spatial distribution ...
