CT based encryption 1. Open contourlet 5 and run aaa.m for image decomposition and for denoising 2. Open tsss and A_hidetext.m and set break point at line 109 and run 3. After selecting image ind text press F5 4. Now run H_finalextra

Color decomposition of colored image in RGB and then conversion into CMY model.

实现的是对明文消息的加密和解密过程，算法是根据大数的因数分解。-Implementation is the plaintext message encryption and decryption algorithm is based on the decomposition of large numbers of factors.
