Content adaptive watermark embedding algorithm using a stochastic image model in the multiwavelet transform is proposed in this paper. Usually, watermark is embedded with the same embedding strength regardless of local properties of the cover image, so the visible artifacts are taken placed at flat regions. A watermark is embedded into the perceptually significant coefficients (PSCs) of each subband...
This paper presents highly reliable adaptive image watermark embedding using a stochastic perceptual model based on multiwavelet transform. To embedding watermark, the original image is decomposed into 4 levels using a discrete multiwavelet transform, then a watermark is embedded into the only JND (just noticeable differences) of the image each subband. The perceptual model is applied with a stochastic...
