遥感影像的分块程序，调用opencv和openssl，在实现切块的同时计算每块的哈希值，哈希算法采用MD5，分块数量可以通过更改宏定义设定- remote sensing picture cutting program based on opencv and openssl，which can also calculate the file hash with MD5

在本系统中通过MD5的方法实现对任意文件的属性查看，并将结果保存在任意位置一文本文件的形式。-In the present system to achieve the properties view arbitrary files via MD5 method, and the results stored in the form of a text file anywhere.
