Performance of an ICA video watermarking scheme using informed techniques
Independent component analysis (ICA) techniques have been recently used in different watermarking schemes. However, performance of an ICA video watermarking scheme in comparison with those using classical domains, such as the discrete Fourier transform (DCT) domain, is still not clear. In this paper, we attempt to fill this gap. Therefore, we propose a video watermarking scheme, using an informed trellis, applied in two transformed domains obtained by using respectively the DCT transform and an ICA coding technique. We show that, for both domains, the scheme offers a good robustness against MPEG-2 compression, 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.
