用idl计算图像的信息熵，对遥感图像融合有很大的意义-Idl computing the information entropy of the image, have great significance for remote sensing image fusion

在数字图像处理中，运用MATLAB中的函数entropy可以计算图像的熵或灰度出现的概率-The probability of occurrence in digital image processing, the use the MATLAB functions entropy can calculate the entropy of the image or grayscale

利用C++语言编程，用两种方式，从独立概率与关联概率两个方面分别计算一个图像图像熵。(A program used for computing the entropy of a picture.)
