In Pattern Recognition, vol. 36, 2003, Hou proposed a four-share visual cryptography
scheme for color images. The scheme splits a secret image into four shares, the black mask and
the other three sh...

A visual cryptography scheme encodes a black & white secret image
into n shadow images called shares which are distributed to the n participants.
Such shares are such that only qualified subsets of ...
