Abstract
As to the digital watermarking based on local feature is lack of robustness to non-scaling attacks,this paper put forward a watermarking algorithm based on template and local feature.Firstly,the template information was used to correct the non-scaling attacks.Then the Harris-Laplacian detector was utilized to extract steady feature points from the host image,and the local feature regions area were determined adaptively according to the feature scale theory;finally,the digital watermarks were embedded into the local feature regions using cirque quantization.Experimental results show that the proposed scheme is not only invisible and robust against common signals processing,but also robust against the geometric attacks,in particular,the non-scaling.
