Efficient subpixel image registration by crosscorrelation. This code gives the same precision as the FFT upsampled cross correlation in a small fraction of the computation time and with reduced memory requirements

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

编写相关系数匹配程序，实现计算机同名点自动量测，体会影像匹配初步过程。-Write correlation coefficient matching procedures, the computer automatically measured tie points, experience initial process image matching.

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.
