Abstract
This paper proposes a scheme of digital image watermarking based on the combination of discrete wavelet transform (DWT) and independent components analysis (ICA). Firstly, the original image is decomposed by DWT, and then the approximate sub-image of the original image is mixed with the watermark directly. The scheme can embed all the information of watermark into the image, and can also extract all the characteristic information of the watermark by using ICA. The simulation results demonstrate that this scheme with high robustness.
