说明：  算差分盒维数的matlab程序。 让窗口中的每个像素都对分数维作出贡献。首先,计算某一尺度窗口的平均灰度值 ,然后判断每一个像素的灰度 ,若大于灰度平均值 ,则累加其灰度值为 max ,若小于灰度平均值 ,则累加其灰度值为min ,用max 和min代替 在 Sarkar 和 Chaudhuri 算法中的最大值和最小值 ,再通过拟合求出分数维。 (Differential count box dimension matlab program. Let window on the fractal dimension of each pixel to contribute. First, the calculation of an average gray scale of the window, and then determine the gray scale of each pixel, if the intensity is greater than the average, the cumulative value of its gray max, if less than the average gray level, the accumulation of its gray value of min, max and min to use instead of the algorithm in Sarkar and Chaudhuri maximum and minimum, and then by fitting the calculated fractal dimension.)

辛普森公式的自适应积分：在整个积分区间使用相同的小步长 ，以保持整体精度。然而，实际应用中，函数的振荡起伏的情况处处不同，这并没有考虑到曲线的某些部分变化剧烈，需要比其他部分多加考虑的情况。而有些部分，曲线的变化缓和，因此可以采用大于平均值的步长 来进行积分。因此，引入一种能够在函数值变化大的区间采用小步长的方法是很有用的。这种方法，称为自适应积分。(Adapt integral based on Simpson integral)
