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! <br /> http://www.programmersheaven.com/mb/Algorithms/427221/427221/basis-matrices-in-visual-cryptography-scheme/ Sat, 04 Feb 2012 08:49:54 -0700 Algorithms http://www.programmersheaven.com/mb/Algorithms/427221/429712/re-basis-matrices-in-visual-cryptography-scheme/#429712 <span style="font-size: xx-small;"><strong>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.
