Concatenating the subsets yields a dither matrix that reproduces a motif while displaying an overall image. ...
It also improves artistic halftoning, by extending the range of viable motif images that may be repeated when reproducing an overall image. ...
As far as the present author is aware, graph ordering has not been previously applied to the problem of halftoning. ...

Visual cryptography (VC) is an encryption technique for hiding a secret image in distributed and shared images (referred to as shares). ...
We propose an approach to hide multiple images in meaningful shares. We can decrypt multiple images simultaneously using a common share, which we refer to as a magic sheet. ...
Contrast-aware halftoning [22] or other stateof-the-art error diffusion approaches [23] could also be employed for faster and better image preparation. ...
