Different positions of box-grid were found to significantly affect the measurement of FD (p < 0.0001, d = 0.746) due to non-identical vessels captured for measurement. By averaging multiple box-grid placements the FD mean shows no significant difference (p = 0.12, d = 0.124). Using ...

box-counting fractal dimensionimage segmentation and classificationThe paper presents the application of the box-counting dimension to the recognition of hypertension through the analysis of th e image of the eye fundus. The box-counting dimension represents a single measure, often used to describe ...
Fractal nests are sets defined as unions of unit $n$-spheres scaled by a sequence of $k^{-\\alpha}$ for some $\\alpha>0$. In this article we generalise the concept to subsets of such spheres and find the formulas for their box counting dimensions. We introduce some novel classes of...

In the research of fractal cities, the fractal dimension is very important. It is used to describe the fractal character of the city. The authors have designed two approaches to calculate the fractal dimension by the box-counting method through an example of Beijing, which are called the vector...
