A Content Adaptive ICA Watermarking Scheme Based on DWT-SVD Domain
Tao Zh · Microcomputer Information · 2010
The paper proposes an adaptive watermarking algorithm based on DWT-SVD domain.The original image is transformed into discrete wavelet domain.The watermark is embedded into the singular value decomposition of the approaching sub-image with different strength according the noise visibility function of the sub-image by the independent component analysis.Experimental results show that the algorithm has good robustness against noise, normal image processing, image compression.
