An ICA based algorithm for video watermarking
In this paper, a new video watermarking scheme is proposed. We adapt two watermarking algorithms, originally proposed for still image watermarking, to embed data in a set of statistically independent sources, extracted from a video sequence. We show the interest of applying such an approach to video watermarking. The proposed scheme offers good robustness against MPEG compression attack, as well as an important capacity level. We consider, in this paper, data hiding in digital TV channels where data are compressed using MPEG-2. The main contribution of our study is to compare two different watermarking approaches applied to error prediction frames transformed by ICA.
