In order to solve the imbalance between watermark hiding degree and robustness in the watermarking algorithm,the quick response (QR) code and holographic technology are combined in the Contourlet-SVD domain.A digital holographic watermarking algorithm based on QR code in the Contourlet-SVD domain is proposed.First,the different carrier images are chosen to perform 3-layer Contourlet transform.In view of the advantage of low frequency coefficient,the singular value decomposition (SVD) joint transform is performed for the low frequency coefficient.Second,the QR code which is encoded by “Flight School” image is chosen as the original watermark image.The QR code holographic watermark is obtained by conjugating symmetry extended Fourier digital hologram.Thirdly,the holographic watermark is superimposed on the singular value obtained by SVD to complete the embedding of the watermark information.The simulation experiment proves that the image clarity of the algorithm is better after embedding the watermark information.The peak signal-to-noise ratio (PSNR) value of the algorithm is above 31 dB.The similarity normalized correlation (NC) of the algorithm reaches 0.989 0.The extracted watermark information can be clearly identified after the image has been tested against resistance.The NC values all reach above 0.90 especially for salt and pepper noise,Gaussian noise and mid-pass filtering attacks.
