将RGB图像转化成灰度图像，并利用灰度共生矩阵计算熵特征图像。-RGB image is converted to grayscale images, and calculate the entropy feature image use GLCM.

表示出两帧图像间各个像素点的相对情况，pwm整流器的建模仿真，经典的灰度共生矩阵纹理计算方法。- Between two images showing the relative circumstances of each pixel, Modeling and simulation pwm rectifier Classic GLCM texture calculation method.

首先使用灰度共生矩阵提取图像纹理特征，之后使用灰度共生矩阵的熵值与相关性系数作为纹理参数，用k-means聚类算法实现遥感图像的云检测-First of all, the gray co-occurrence matrix is used to extract the image texture features, then the entropy and correlation coefficients of the GLCM are used as texture parameters, a
