分形维度(Fractal Dimension)是用于描述分形几何结构的复杂度的一个量化指标。简而言之,它衡量了一个形状的复杂性或者自相似性。常用的方法是使用盒子计数法(Box-Counting Method)来计算分形维度。 假设我们有一个二维图形,我们可以通过将其覆盖在一个网格上,并计算不同尺寸的盒子所包含的图形的数量,从而来估计它的分...
Forty retinal vasculature images from publicly available dataset were subjected to four variations of box-counting FD algorithm. 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. ...
第二,对分形理论的数学基础进行了较系统的分析研究,特别是对分形维数的理论和计算进行了较深入的分析和比较,采用了目前常用的盒维数计 算(BoxCounting)方法,详细讨论了基于改变粗视化程度求分形维数的方法,并对结果进行了一些误差分析。 第三,通过对分形插值方法的研究,研究了IFS线性分形插值生成分形图像的方法。
Box-HeightSelf-SimilarityFractal Dimension (FD) estimation in digital image analysis has received much attention due to its dimensional significance and therefore has become an active area of research over the year. The earlier FD based techniques often followed traditional box-counting and its ...
Box counting analysis is the simplest method that can be used to estimate a fractal dimension. The pattern under analysis is covered by a quadratic grid. The size of the grid cells increases from one iteration step to the next. Considering each grid cell size 腿 the number of cells N% con...
The box counting dimension changes whenever a new point falls within an empty circle. This happens only when a new subsequence appears in the data. It is therefore reasonable to assume that the box counting dimension would be a good statistic to detect outliers. However, the box counting ...
These results motivate further research that may explain the unintuitive behaviour of box counting dimensions for nest-type fractals, and in general the class of sets where the box-counting dimension differs from the Hausdorff dimension.doi:10.1016/j.chaos.2018.05.025Sinia Milii...

As such, the reliability of fractal dimension estimates can also be increased through the application of different methods on a given swimming trajectory. In addition to the box-counting method, two conceptually similar methods described below are very well adapted to the characterization of swimming ...
