Error Filtering Schemes for Color Images in Visual Cryptography

Shiny Malar, Jeya Kumar
2011 International Journal of Advanced Computer Science and Applications  
The color visual cryptography methods are free from the limitations of randomness on color images. The two basic ideas used are error diffusion and pixel synchronization.  ...  The proposed color image visual cryptic filtering scheme presents a deblurring effect on the non-uniform distribution of visual cryptic share pixels.  ...  The limitation of the above method is its randomness without any visual information. Extended Visual Cryptography have been suggested which also suffers from the same drawbacks of randomness.  ...
