Abstract :
The Barni method has been proposed in the literature for watermarking still images. In our previous work, we have extended this method to work for image sequences (video). However, it was found that this extended frame-based version fails under video compression attacks. In this paper, we present a block-based version to improve robustness against such attacks.
