This program generates a two-out-of-two Visual Cryptography Scheme shares. The input image for this program should be a binary image. The shares and the overlapping result of the shares are written as output. The Shares (1 & 2) can be printed in separate transparent sheets and overlapping them reveals the secret image.
if i want 3 shares. then i each pixel would be divided into three shares, so that should make the size of each share 3 times the original image. But i am getting the results for just wice the size. I am not able to understand the concept?
Is there a way to use this so a single share1 image can complement multiple share2 images resulting in distinct overlap images?
sir how do i do for multiple share
Sir What is the difference in the effect of 4 shares and 6 shares.
sir how to apply vcs to color face images.. relpy me fast sir
sir how to apply vcs to color face images.. rely me fast sir
please reply me fast. Sir...
what is the meaning of the code portion"
and is the pixShare is a variable which is userdefined or it is a function from matlab library.
I want code for 2 out 3 sheme sharing visual cryptography,can you explain the code u used in 2outof 2 scheme, the line is share1((a),(2*b-1):(2*b))=pixShare(1,1:2); pls?
I have the same question as how to generate the same shares for colour images.
sir how to generate the same shares for colour images. shares of red green and blue. den combining them to get colour visual cryptography
Why pixel expansion 2 is used?. Comments not enough.
Open source is way the technology free to learn, not just code.

Code without proper comments is a Bread without jam
It is quite interesting could u tell me how to do it for 3 out of 3 scheme
Quite Interesting. Its working for my own images.

The first two columns of the share were always "0" in the previous release. The file "VisCrypt.m" has been updated to fix this issue.
