基于混沌序列的加密系统，这里只是针对位图，但是明白混沌加密的原理后可以采用opencv图像处理库进行修改。-Based on Chaotic Sequences encryption system, where only the bitmap, but understand the principle of chaotic encryption can be used after opencv image-processing library to edit.

opencv中用于解压图像文件的工具，如果没有此工具，opencv处理图像的时候会出现错误。-opencv image file decompression tool used, if not this tool, opencv image processing when an error occurs.
