A robust blind watermarking algorithm for depth-image-based rendering 3D images

作者：

Highlights：

• A robust blind watermarking algorithm for depth-image-based rendering 3D images is proposed.

• The watermarked image has good perceptual quality under both the objective and subjective image quality evaluations.

• The proposed algorithm is robust to image processing distortions and view synthesis process.

• The proposed algorithm shows superiority over other related methods in terms of image fidelity and watermark extraction.
