This paper presents a public watermarking algorithm combining single value decomposition(SVD)with neural network.We firstly use block single value decomposition to every block of original image,and then establish the relational model of neural network between the biggest single value coefficient and other coefficients.Finally a bit of the watermark is embedded by adjusting the polarity between the biggest value coefficient and the output value of the model.Experiment results show that this algorithm has good transparence of the embedded watermarking and is robust to attacks such as JPEG compression,smoothing,noise adding,and sampling.
