An adaptive watermarking method based on discrete wavelet transform is proposed in this paper. To get good
imperceptivity and robustness, the energy of sub-blocks and the texture of the carrier image have been used to determine
where the watermark will be embedded. And the watermark embedding intensity will be determined by the noise visibility
function. Experimental results show that this method is effective.
