New Relationship-Based Stereo Image Watermarking Algorithm for 3D Media

摘要

In this paper, a relationship-based stereo image watermarking algorithm is proposed to protect copyright of three dimensional media. The biggest difference between stereo images and two-dimensional pictures is that there is a relationship between viewpoints of stereo image. The proposed algorithm is not only embedding watermark in left image, but also embedding watermark in right image by quantifying the differences between discrete wavelet coefficients of watermarked left image and right image. The innovation of the algorithm is to embed watermark messages by using the relationship of stereo images, and it also can be applied to protect copyright of single-channel video. Experimental results show the effective of the proposed algorithm.
