Abstract

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.
