Digital Image Watermarking Algorithm Based on Wavelet Transform and the NMF

摘要：

A kind of combination of wavelet transform and NMF of digital watermarking algorithm is proposed in this paper. First the original image is transformed by wavelet transform twice. We embed the watermark into the intermediate frequency sub-image by NMF. Combining both of their respective advantages, it will be a good way to solve the weak shearing resistance of the wavelet transformation and the weak robustness of median filter by NMF. Experimental results show that this method has good robustness for other conventional attack.
