Abstract :
Wavelet packets are shown to be a possible means to limit watermark interference in multiple re-watermarking algorithms. It turns out that when demanding a certain distance among wavelet packet subband trees, a significant improvement of watermark detection correlation values may be achieved in such a scenario.
