In this project i have used HALFTONE concept to merge two fake image and get the real image . Halftone is the reprographic technique that simulates continuous tone imagery through the use of dots, varying either in size, in shape or in spacing."Halftone" can also be used to refer specifically to the image that is produced by this process.
This was a project, i developed in 3rd year of my engg. to learn image cryptography , programs are really easy and easy understandable , java language has been used.
