Abstract :
Recently, independent component analysis (ICA) was used to extract image feature. At the same time, the ICA-based watermarking techniques appeared. In this paper, a novel watermarking method is proposed, in which DCT is used to do in-depth processing after ICA to remove the correlation of the elements of the independent components, and then the watermark is embedded into the coefficients. The simulation experiment shows good results.
