Estimation of Fractal Dimension and Statistical Tools for Surface Evaluation

Fractal geometry is a useful tool for describing the complexity of structured data. However, fractal geometry does not substitute for other tools like statistics and should be used with other parameters for general analysis. Hence, the sensitivity to changes in complex data is studied here. For this purpose, samples with structured surfaces produced with different technologies and properties were measured and evaluated with many types of parameters. The parameters were compared and a selection of the results is presented in this article.
