MATLAB code of steganography based on contourlet transform

Hello, Friends today posing one project based on information security. The title of the code is steganography based on contourlet transform. The developed algorithm comprises the following steps.

-- Take the cover image

-- Take the secrete image

-- Apply contourlet transform on cover image.

-- Compress secrete image, it has two options lossy compression and lossless compression, user can choose one from two.

-- Embed compressed secrete image into contourlet coefficients of the cover image
