Simple reversible watermarking schemes


This paper proposes a low computational reversible watermarking approach. An integer transform is defined for pairs of pixels. The transform is invertible and, besides, for some pairs of pixels, the original values are recovered even if the LSBs of the transformed pixels are overwritten. This allows watermarking embedding into image LSB plane without any… (More)
