Optimization of multi-scale segmentation of satellite imagery using fractal geometry

International Journal of Remote Sensing, 2019
After decades of research, optimal scale selection for image segmentation remains a key scientific problem in image analysis. In order to contribute to a solution, a new method was developed in this research, based on the use of fractal dimension as an ...

Compact high gain UWB antenna using fractal geometry and UWB‐AMC

Microwave and optical technology letters (Print), 2018
A miniaturized fractal antenna using Coplanar Wave Guide (CPW) fed and ultrawideband (UWB)‐artificial magnetic conductor (AMC) for ultra wideband and Active integrated application is designed and presented. This antenna covers frequency range from 2.5 to

FRACTAL GEOMETRIES IN DECAY MODELS

Journal of Physics A: Mathematical and General, 1984
Results of computer studies of the geometries produced by two distinct decay models are present. While one of the models (diffusion-limited decay) results in compact clusters, the other (random-walk decay) produces ramified clusters with the Hausdorf dimension (df) equal to 1.75+or-0.03 and 2.34+or-0.03 in two and three dimensions respectively.

Fractal Geometry of Helicity Amplitude

Fractals, 1997
Fractal geometry is in use to get lucid and visual explanation of many a natural and complex phenomena. High Energy Scattering process is quite complex a happening in science. Several methods are available to explain the events linked with high energy scattering.

The Fractal Geometry of Evolution

Journal of Theoretical Biology, 1993
This study is aimed at showing that the fractal geometry of taxonomic systems (Burlando, 1990) reflects self-similar evolutionary pattern. Evidence is achieved by three steps: (i) examination of taxonomic data from the fossil record; (ii) examination of taxonomic data from phylogenetic systematics; (iii) comparisons among different levels of the ...

The fractal geometry of life.

Rivista di biologia, 2009
The extension of the concepts of Fractal Geometry (Mandelbrot [1983]) toward the life sciences has led to significant progress in understanding complex functional properties and architectural / morphological / structural features characterising cells and tissues during ontogenesis and both normal and pathological development processes. It has even been

Examples of Fractal Geometry

1991
Examples of fractal geometry abound. As mentioned earlier, the fractal dimension, dF, is constrained by the topological dimension, dT, from below and the Euclidean dimension, dE, from above. The fractal dimension of a rugged line on the plane with an Euclidean dimension of 2 is between 1 and 2, as demonstrated in Figure 2–5.
