  • In this paper, a new digital watermarking algorithm based on LU decomposition of matrix is proposed. In order to apply LU decomposition, the corresponding nonnegative matrix of the image is transformed into G-diagonally dominant matrix. In the course of embedding digital watermarking, the scale quantization function is used. The original image is not needed in the recover progress. Experiments are given for contrasting the LU algorithm with DCT mid-frequency coefficient comparison method, and results show that this new-algorithm is robust and easy to embed and extract.
