Robust contourlet-based blind watermarking for depth-image-based rendering 3D images
作者：
Highlights：
• A novel blind watermarking scheme for depth-image-based rendering 3D images is proposed.
• The watermark embedding and extraction are performed in contourlet domain.
• The watermark can be detected with a low bit error rate from the watermarked center view, and the synthesized left and right views even when each view is distorted and distributed separately.
• The proposed scheme is robust to geometric attacks and common DIBR processing.
