MATLAB code of DWT based image Steganography

Hello, friends today posting a new project in the field of information security. There are various types of steganography methods have been proposed by different authors. Some of them are based on LSB, some of them are based on DCT transform. Today's steganography is based on DWT. The working of the code is shown in the following Youtube video. Just have a look.

YouTube Video of the Project:

The following steps are included in this project.
-- Select color cover image
-- Select color secrete image
-- Apply DWT to cover image and decompose a cover image into 4 subbands (LL,LH,HL,HH)
-- Find embedding DWT coefficients from decomposed image 
-- The DWT coefficient finding is based on HVS effect.
-- The quality parameters are taken to find out quality of the stego image. The PSNR and MSE is two quality parameters.
-- At the time of Extraction exactly inverse process is applied.
