A robust watermarking scheme for stereoscopic video frames

In this paper, we propose a digital watermarking method for stereoscopic video frames. A stereoscopic video frame is stored as two images and combined by software while displayed. These two stored images are with high similarity. In the circumstances, it should be taken into consideration to resist coalition attacks while developing a watermarking scheme for stereoscopic videos. As shown in experimental results, the watermark embedded with the proposed scheme is still detectable after common image processing operations such as JPEG compression, Gaussian filtering and sharpening. In the future, we will develop stereoscopic video watermarking methods based on the proposed method.
