Pick some text or image file(grayscale) of your choice, and a colored RGB picture then, do the following:
a) Hide this file into the colored picture by replacing its least significant bits of each color in every pixel with your file data. Try to use a minimum number of LSB bits of the colored picture such that changes are unnoticeable.
b) Restore this hidden picture from the carrier picture.
