A Digital Image Watermarking Method Based on ...

By combining the compressed sensing theory and the digital watermark technology, a digital watermarking method based on the theory of compressed sensing is proposed in this paper. The method is divided into three steps: compressed sensing compression process, compressed sensing recovery process and compressed sensing extraction. The watermarket is embedded through the embedded mechanism between the compressed sensing compression process and the compressed sensing recovery process. The experiments show that the proposed watermark method has stronger robustness and is more safe to against the attacks.
