A DWT-SVD Domain Watermarking Algorithm Based on Feature Template

摘要：

As to the digital watermarking algorithms based on feature points are low of watermark capacity and lack of robustness to non-scaling attacks, this paper put forward a watermarking algorithm based on feature template. First, watermark is embedded in DWT-SVD domain. Secondly, this scheme used the feature points operator to extract the feature points as a template and conserved. During detection this paper used the linear transformation between corresponding points in feature template to realize resynchronization. Experimental results demonstrate that the proposed scheme is not only invisible but also robust against general image processing and geometric distortions.
