calculate mean value os a rasterlayer under a polygon layer

遥感影像融合精度评价程序 均值、方差、相关系数、熵、清晰度-Remote sensing image fusion accuracy evaluation procedures mean, variance, correlation coefficient, entropy, clarity

微波遥感中，粗糙度参数均方根高度、相关长度计算公式代码-Microwave remote sensing, the parameters of the root mean square roughness height, correlation length calculation formula of the code

这个程序可以对融合影像进行定量评价。可以得到影像的影像均值,偏差指数,信息熵,平均梯度,相关系数,光谱扭曲程度是。-This program can be fused image quantitative uation. Video images can be mean deviation index, entropy, average gradient, correlation coefficient, spectral distortion degree yes.
