Comparison of Various Error Diffusion Algorithms Used in Visual Cryptography with Raster Scan and Serpentine Scan
Digvijay Singh,  Pratibha Sharma
This paper represents the encoding of secrets image into halftone image with in the scheme of Visual Cryptography. Halftone generation is the first step in the Visual Cryptography. Visual cryptography is a cryptographic technique which allows optical information to be encrypted. A particular halftoning method named as error diffusion method is used for the better generation of halftoned image .Here we can use 3 error diffusion algorithms with raster scan and serpentine scan in order to generate halftone of secret image. Simulation results shows which algorithm is best for halftone generation as compare to others with raster scan and serpentine scan.
Keywords- Error Diffusion, Half toning, Raster scan, Serpentine scan, PSNR, WSNR, LDM, UQI.
