Steganography based on wavelet transform MATLAB code

Hello, Guys posting one project in the field of information security. This project is about steganography based on wavelet transform. The methodology of the data hiding method is very simple and easy to understand. The output results shows that this steganography is robust and imperceptible. The MATLAB implementation of this project is shown in the following YouTube video. Just have a look.

YouTube Video of the Project:  

The following steps are involved in the MATLAB implementation of this wavelet-based steganography.

-- Read Input Grayscale cover image.
-- Read binary secrete image. 
-- Decompose cover image into its four subbands Approximation, Horizontal, Vertical and diagonal (LL,LH,HL,HH).
-- Convert secret image into the binary data stream.
-- Select possible embedding points from LL, LH and HL subbands.
-- Embed secrete bits into the selected embedding points.
-- Calculate various image quality parameters like PSNR, MSE etc.
-- The exactly reverse process is applied at the time of extraction.
