Reversible Data Hiding using Increased Peak Histogram

In this paper, we present a reversible watermarking algorithm which provides higher embedding capacity and higher PSNR value compared to the existing algorithms. In the proposed algorithm, we utilize a peak point of image histogram and increase the height of the peak by transferring the pixels from...

Description
Summary:In this paper, we present a reversible watermarking algorithm which provides higher embedding capacity and higher PSNR value compared to the existing algorithms. In the proposed algorithm, we utilize a peak point of image histogram and increase the height of the peak by transferring the pixels from the neighbouring gray values to achieve the higher embedding capacity.
