基于傅里叶变换的数字盲水印加解密
加密文件encode-python.py,
解密文件decode-python.py
依赖环境：python+opencv
命令行参数 encode：
--image [源文件]
--watermark [水印文件]
--result [生成目标文件地址]
[--alpha 混杂强度]
decode:
--original [源文件]
--image [待解密文件]
--result [水印生成文件地址](Digital blind watermark based on Fourier transform- python.py , Decrypt file- python.py　Dependency environment: Python + opencv command line parameter encode: -- Image [source file] - watermark [watermark file] - result [generate target file address] [-- alpha hybrid intensity] decode: -- original [source file] - image [to be decrypted file] - result [watermark generate file address])
