摘要：
A new digital image watermarking technique in wavelet domain is proposed. In embedding process this method uses scrambling, extension and mean removal technique to original watermark then watermark is embedded in middle frequency sub-bands of original image. The embedded strength of watermark is determined adaptively by noise visibility function. In extraction process this method adopts independent component analysis and doesn't need any information about original image and original watermark. The experimental results show that this method has a good robustness to wide variety of attacks.
