A novel watermarking scheme against geometrical distortions based on Contourlet transform

摘要：

This paper proposes a design for data hiding in digital image that robust with both geometric and common signal attacks. We combine scale-invariant feature transform with Neighborhood Pixel Ratio domain to embed resynchronized information so watermarked image can be reconstructed under geometrical attacks. The Contourlet-based algorithm is used to hide message into Contourlet transform domain. It can get a high robustness level to against other common attacks. The experiment results show that our proposed scheme is strong robustness when sensible combining above algorithms.
