A New Scheme of Digital Watermarking Based on Independent Component Analysis
Xingang Zhang · Dianzi xuebao · 2004
The research on digital watermark is a focus of multimedia signal's processing. So far, there have been many methods to embed and extract watermark. What is important to digital watermark is how to improve its robustness. In this paper,the independent component analysis (ICA) is used in our watermark scheme, that is, we mix the host image and the watermark directly in spatial domain and then use ICA to extract the watermark. We get excellent simulated results.Hie simulated results show that it is a new method with very outstanding robustness.
