Steganography

My C program example input & output

A deer — Img A - Container Image

A snail — Img B - Image to be encoded

A deer image having another image encoded into it by steganography using 2 most significant bits of the RGB values — Img C - Output image after encoding Img B into Img A using 2 bits of the RGB values. Looks almost identical to the original image.

A snail image output of steganography decoding using 2 most significant bits only — Img D - Output image after decoding Img C. Some quality has been lost.

A deer image having another image encoded into it by steganography using 7 most significant bits of the RGB values — Img E - Output image after encoding Img B into Img A using 7 bits of the RGB values. Alteration can be seen.

A snail image output of steganography decoding using 7 most significant bits — Img F - Output image after decoding Img E. Looks almost identical to the original image.
