说明：  用于分块的octave程序，也能在matlab上运行（需将其中的resize函数改成imresize）。 该程序可以将图片于横向与纵向分割出任意块数。 包括用于分割的文件，和封装好可以直接调用的函数，以及一个示例图片。 希望能对初学者有所帮助。
(The octave program used for blocking can also be run on MATLAB (the reset function needs to be changed to imreset). The program can divide the image into any number of blocks horizontally and vertically. Including the file used for segmentation, and packaged functions that can be called directly, as well as a sample image. Hope to help beginners.)
