Abstract :
A watermarking energy estimating model in wavelet domain is proposed in this paper. The model novelly expresses the special relationship between the watermarking energy and the PSNR(or SNR) of the watermarked image in wavelet domain, and the PSNR(or SNR) can be computed by the watermarking energy rather than by the watermarked image, so that the quality of the watermarked image can be directly controlled by the embedding strength and watermark. At last, the experimental results verify the relationship proposed in the paper.
