分形分析在图像处理中被证明是有用的，可以在从电子到医学工程的不同应用中描述形状和灰度复杂性（例如[1]）。分形分析由几种方法组成，用于为描述几何对象的数据集分配维数和其他分形特征。分形分析在土壤颗粒形状特征分类中的应用研究较少。本文所描述的工作的主要目标是获得，从人工简单形状的系统分形分析的结果，在不同尺度的颗粒形态的表征。研究的长期目标是将粒状介质的微观特征与实验室和现场观察到的力学行为联系起来。
Fractal analysis has been shown to be useful in image processing to characterise the shape and the grey-scale complexity in different applications spanning from electronic to medical engineering (e.g. [1]). Fractal analysis consists of several methods to assign a dimension and other fractal characteristics to a dataset describing geometric objects. Limited studies have been conducted on the application of fractal analysis to the classification of the shape characteristics of soil grains. The main objective of the work described in this paper is to obtain, from the results of systematic fractal analysis of artificial simple shapes, the characterization of the particle morphology at different scales. The long term objective of the research is to link the microscopic features of granular media with the mechanical behaviour observed in the laboratory and in situ .
