A New Image Watermarking Scheme Using Saliency Based Visual Attention Model
In this paper, a new spatial domain adaptive image watermarking scheme is proposed which embeds watermark information to the least salient pixels of the image. Watermarked image thus produced has less perceptual error with respect to human visual system (HVS). In proposed scheme least salient pixels are determined using the well known Itti-Koch model. Experimental results reveal that proposed scheme has less per- ceptual error than existing spatial domain embedding scheme.
