图像融合评价指标，包括有：均值，标准差，信息熵，平均梯度，相关系数，扭曲程度，偏差指数。每个指标都分别对RGB三个波段进行评价。-This file refers to the ution factor of image fusion,which including:mean,standard deviation,information entropy,average gradient,correlation cofficient,distortion and bias index.Each

图像融合中的平均梯度、相关系数、信息熵、交叉熵、联合熵、均方误差、互信息、信噪比、峰值信噪比、均方根误差、空间频率、标准差、均值、扭曲程度、偏差指数等等(Evaluation indexes average gradient, correlation coefficient, entropy, cross entropy, joint entropy, mean square error, mutual information, signal-to-noise ratio, peak sign

可以用来评价两幅图像灰度图直方图的相关度，得到结果可以用来分析有噪声和无噪声图像的不同(Can be used to evaluate the histogram correlation of two image grayscale histograms, and the results can be used to analyze the difference between noisy and noiseless images)
