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 ...
TOWARD REDUCTION OF ARTIFACTS IN FUSED IMAGES
Most fusion satellite image methodologies at pixel-level introduce false spatial details, i.e. artifacts, in the resulting fused images. In many cases, these artifacts appears because image fusion methods do not consider ...
Análise fractal da vasculatura arteriolar e venular da retina em pessoas sem doença ocular
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciências da SaúdeCiências da Saúde, 2008-05-13)
Although it has been suggested that retinal vasculature is a diffusion-limited aggregation (DLA) fractal, no study has been dedicated to standardizing its fractal analysis . The aims of this project was to standardize ...
Sets which are not tube null and intersection properties of random measures
(Oxford University Press, 2015-02)
We show that in ℝd there are purely unrectifiable sets of Hausdorff (and even box counting) dimension d - 1 which are not tube null, settling a question of Carbery, Soria and Vargas, and improving a number of results by ...

Fractal dimension applied to plant identification
(ELSEVIER SCIENCE INC, 2008)
This article discusses methods to identify plants by analysing leaf complexity based on estimating their fractal dimension. Leaves were analyzed according to the complexity of their internal and external shapes. A computational ...
Dimensão fractal na quantificação do grau de rejeição celular miocárdica pós-transplante cardíaco
(Sociedade Brasileira de Cirurgia Cardiovascular, 2011-06-01)
INTRODUÇÃO: O termo fractal é derivado do latim fractus, que significa irregular ou quebrado, considerando a estrutura observada como tendo uma dimensão não-inteira. Há muitos estudos que empregaram a Dimensão Fractal (DF) ...
Identification of quantitative trait loci affecting resistance to gastrointestinal parasites in a double backcross population of Red Maasai and Dorper sheep
A genome-wide scan for quantitative trait loci (QTL) affecting gastrointestinal nematode resistance in sheep was completed using a double backcross population derived from Red Maasai and Dorper ewes bred to F1 rams. This ...
