The aim of this demonstration is to present the ongoing performance of our R. and D. watermarking scheme software. The proposed illustrations cover a large panel of original image...
Abstract-- We present a perceptual model for hiding a spreadspectrum watermark of variable amplitude and density in an image. The model takes into account the sensitivity and maski...
