# Basis Matrices in Visual Cryptography Scheme

Posts: 1Member
Hey everyone,
I'm doing my final year project on Visual Cryptography, and I'm basing it off the paper below:
http://lbms03.cityu.edu.hk/theses/c_ftt/mphil-cs-b39478154f.pdf

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!

[size=1][b]Hello. I am a student and want to do research in this field. I am also stuck at basis matrix construction, since u were doing final year project, i am sure you must have done it till now. Kindly help me. I am sure you will be kind enough to feel the way I am feeling because you have gone through this time. So please guide me the construction method of the basis matrix. Thanks Alot.
