Abstract :
Using communication theory tool sets based on diversity and channel estimation improves the performance of robust digital watermarking algorithms. This article demonstrates that algorithms employing some form of watermark redundancy can be significantly enhanced. It also discusses effective data hiding strategies within the proposed framework and reports on the results of robust reference watermarking
