Research on Stereo Image Authentication Watermarking with Self-recovery
With rapid development of three dimensional video systems, the integrity of stereo image has become increasingly important. However, stereo image authentication watermarking methods are rarely reported, and only monocular watermarking methods are extensively studied. In order to ensure authentication and integrity of stereo image, different stereo image watermarking methods are presented in different ways. Firstly, existing monocular watermarking methods are extended directly to stereo image without correlations of stereo image. Secondly, monocular image watermarking methods are extended further as that disparity is used to recover tamper. Finally stereo vision based stereo image watermarking methods are proposed for embedding more recovery bits to improve tamper recovery. Experimental results show that stereo image watermarking method based on correlations of stereo image can improve watermarking performance.
