Abstract:A wavelet transform digital image watermark scheme combined with zero-watermark is given. It takes the advantage of the zero-watermark scheme, which has a good robustness againstthe image processing, and the image watermark scheme in the wavelet-domain has more persuasion. The experiment results show that the scheme has a good performance in the image processing such as filtering, additive noise, compression and cropping.
Keywords:image watermark  zero-watermark  wavelet transform
