摘要：
In this paper independent component analysis (ICA) is used to test the robustness of watermarked image. By applying suitable ICA forward transformation, the distributions of the cover image and the watermark are modified. The cover image and the watermark are estimated by using a nonlinear filter and the inverse transform matrix. The preliminary experiments show that ICA attack not only influences the hidden information but also improves the image quality for reasonable embedding strengths.
