- W2183613131 abstract "Imagedatahiding isthehiding ofinvisible patterns inanimagewithout degrading itsvisual quality. The hidden pattern canbevisualized byoverlaying the original image with watermarked onesorbyapplying an extraction algorithm. Ifthehidden pattern isvisualized using theoverlaying method, itcanalsobevisualized using asimple XNORoperation. Inthecasethat hidden dataisextracted byaspecific algorithm, itiscommonly called steganography. Inthis paperwepropose a methodcalledDot Diffusion withNonlinear Thresholding (DDNT)toembedhidden datainhalftone images, wherethehidden datacanbeextracted by overlaying original andwatermarked images orby performing theXNORprocess onthese twoimages. The mainadvantage ofthismethodisthatthehidden pattern's intensity canbeadjusted bythree parameters. TheDDNT datahiding methodutilizes theinherent parallelism indotdiffusion halftoning method, although itsuffers fromitslower visual quality thansomeother halftoning methods suchaserror diffusion." @default.
