Abstract :
In this paper, an adaptive spatial domain image watermarking scheme is proposed which embeds watermark information to the uneven bit depth salient image pixels. Watermarked image thus produced has better visual transparency with respect to human visual system (HVS) with high payload capacity. In proposed scheme, salient pixels are determined using the bottom-up Graph-Based Visual Saliency (GBVS) model. Experimental results reveal that proposed scheme has less perceptual error as well as improved robustness than existing spatial domain embedding scheme.
