I want know this algorithm loss data after hid text ( message ) in HH or LL , why when hid text and apply inverse , image is very different about original image , I am using edge detection for hid , and not found paper about this algorithm hid text , only hid image or audio , so this not work in hid text ???
Dear Sally Adnan Al Temimi
The low image visual quality you have gained comes from using portion of image pixels ( Edge of image). So, you have either to pre-process the payload or the cover image.
Please encrypt and compress the payload before the embedding process. Also, thing about converting the 8 bits of each image pixels into 12 bits using Fibonacci decomposition, it helps you to increase the capacity while maintaining the imperceptibly.
please feel free to ask if need more information.
