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.The simulated results show that it is a new method with very outstanding robustness.
