Wavelet Digital Watermarking Algorithm on the Basis of SVD Decomposition

Abstract:

Based on SVD decomposition, an digital watermarking algorithm with the method of wavelet transform is proposed. By means of singular value decomposition to realize blind extracting, the watermarking image is embedded into intermediate frequency sub bands of wavelet composition. Finally, applying normalized cross-correlation function (NC) and peak signal to noise ratio (PSNC), it has proved that this algorithm has better invisibility and robustness.
