I'm doing my final year project on Visual Cryptography, and I'm basing it off the paper below:
I coded everything, according to what's described in section 3, but the output seems to be off. I have a feeling I messed up the contents of the Basis Matrices B0 and B1(PDF page 41/86). What's more, I can't understand their construction, and the paper fails to specify its contents even for the example they've shown (2-out of-2 color VCS for Lena image). It's so ambiguous I can't even figure out if it should be a 2x2 or 2x4 matrix. Some help would be appreciated!
