Description
Summary:In this paper, human visual system based adaptive LSB replacement process has been used to develop an image watermarking scheme. A saliency map of the cover image is built up and the watermark is adaptively embedded into that cover image pixels to get a better visual transparency with increased payload. In this approach, the saliency map is generated by using a binary and holistic image descriptor, termed as Image Signature. The hardware execution of this proposed methodology has been set up through Virtex6 FPGA board (xc6vlx760). The experimental results divulge that the proposed framework provides less perceptual inaccuracy with improved payload capacity.
