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

用C++模板编写的利用哈希表实现的简单缓存，并利用这个缓存编写了一个快速的图片查看器，希望对初学缓存的朋友带来帮助。-With written in C++ template simple cache hash table and use this cache to write a quick picture viewer, to help bring hope for beginner cache friend.
