A multi-scale image watermarking based on integer wavelet transform and singular value decomposition

作者：

Highlights：

• A novel watermarking scheme based on IWT and SVD is proposed.

• An optimized authentication mechanism is developed to address the FPP.

• Three-dimension optimal mapping is proposed to obtain optimal scaling factors.

• The proposed algorithm can be applied to watermarks with different sizes.

• Results demonstrate a good performance in both invisibility and robustness.
