Abstract :
In scalable image coding-based content adaptation, such as, JPEG 2000, the quality scaling is performed by a quantization process that follows a bit plane discarding model. In this paper we propose a robust blind image watermarking algorithm by incorporating the bit plane discarding model. The new wavelet based binary tree guided rules-based watermarking algorithm is capable to retain the watermarking information for a given number of bit plane being discarded. The experimental simulations confirm the scheme´s robustness against JPEG 2000 quality scalability.
