分形维数作为科学研究的重要工具之一,它是描述自然界和非线性系统中不光滑和不规则几何体的有效工具,其 计算方法已经有多种,应用领域也是十分广泛。然而,各种方法各有不同,文中就此对常用分形维数计算方法进行了系统 的综合与研究,主要包括圆规法、明科斯基方法、变换方法、盒子计算方法、周长- 面积法、裂缝岛屿方法、分形布朗模型法, 对每种方法的含义和模型及相关的应用领域进行了阐述,并给出了其方法的计算机实现算法。-As one of science study tools ,fractal d

A set (e.g. an image) is called "fractal" if it displays self-similarity: it can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole. A possible characterisation of a fractal set is provided by the "box-

ANN是一个构造数据索引结果的程序，可以实现最近邻、KD树等功能。ANN is designed for data sets that are small enough that the search structure can be stored in main memory (in contrast to approaches from databases that assume that the data resides in secondary storage). Points ar
