直方图特征的计算，包括方差，峰度，熵值等。-Histogram of the characteristics of the calculation, including the variance, kurtosis, entropy and so on.

本程序使用matlab实现提取了很多直方图所需要的参数特征，如均值、方差、偏度、峰度、能量和熵。-This procedure used to achieve extracted a lot of matlab histogram parameters needed features, such as the mean, variance, skewness, kurtosis, energy and entropy.
