A highly robust two-stage Contourlet-based digital image watermarking method
作者：
Highlights：
• The first truly blind two stage watermarking method.
• We embedded signature in high and low frequency CT coefficients to increase the range of robustness.
• We embedded signature in local and global CT coefficients to increase the range of robustness.
• We efficiently embedded the signature to achieve low PSNR degradation of watermarked image.
• The proposed blind watermarking method achieves high robustness against wide range of attacks.
