Description: 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-counting" method: The number N of boxes of size R needed to cover a fractal set follows a power-law, N = N0 * R^(-DF), with DF<=D (D is the dimension of the space, usually D=1, 2, 3).
DF is known as the Minkowski-Bouligand dimension, or Kolmogorov capacity, or Kolmogorov dimension, or simply box-counting dimension.

Description: kstest_2s_2d.m:功能做两样本的二维Kolmogorov - Smirnov检验
它类似于MATLAB的内置函数的“kstest2“从统计工具箱除了“kstest_2s_2d“与二维数据处理。
[小时,pValue,KSstatistic] = kstest_2s_2d(为x1,x2,α,尾)
函数在两栏输入“ד,并以“ד,其中每一列代表一个维度。其他的选项和产出是相同的含义,是“kstest2“格式。
摘要算法(峰值,1983年):考虑四个象限(十<的X,Y<Ÿ ),(十<X,y>年),(十>的X,Y<Y)和(x>的X,Y>Ÿ )反过来,采取了两者之间的经验累积分布的四个最后堪萨斯州最大的统计学差异。

It s similar to the MATLAB built-in funtion "kstest2" from Statistics Toolbox except that "kstest_2s_2d" deals with two-dimensional data.
[H, pValue, KSstatistic] = kstest_2s_2d(x1, x2, alpha, tail)
The function takes in 2-column inputs "x1" and "x2", where each column represents one dimension. The other options and the outputs are of the same meaning and format as "kstest2".
Algorithm summary (Peak, 1983): consider the four quadrants (x<X,y<Y), (x<X,y>Y), (x>X,y<Y) and (x>X,y>Y) in turn, and adopt the largest of the four differences between the two empirical cumulative distributions as the final KS statistic.

Please feel free to contact me if you find any bugs in the code. Hope I understood and implemented the ideas in the references correctly...
