  Matlab通过函数imread读取RGB图像，并通过维数m*n*3的矩阵来表示。其中，维数mn表示图像的行数列数信息，维数3表示图像的RGB三层通道数据。因此，全局直方图处理通过对RGB图像的RGB三通道分别进行直方图均衡化，再整合到新的图像的方式进行。(Matlab reads the RGB image through the function imread and is represented by the matrix of the dimension m*n*3. Among them, the dimension mn represents the row sequence information of the image, and the dimension 3 represents the RGB three-layer channel data of the image. Therefore, the global histogram processing is carried out by equalizing the RGB three channels of the RGB image and integrating them into the new image.)
