This paper presents a novel method based on the blind digital image watermarking methods of FRWT and QR decomposition. Compared with the existing DWT domain digital image watermarking method, this method combines the advantages of both FRWT and DWT, which has better flexibility. The simulation results show that the PSNR value of the host image embedded with the watermark is higher than 40dB, which fully demonstrates that the algorithm can not only balance the imperceptibility of the watermark, but also has better robustness against geometric attacks.
