A novel synthetic image watermarking algorithm based on Discrete Wavelet Transform and Fourier-Mellin Transform

Nowadays the digital watermarking technique is presented around the world especially in electronic trade. In this paper, a novel synthetic image watermarking algorithm based on the combination of Discrete Wavelet Transform (DWT) and Fourier-Mellin Transform (FMT) is proposed. To robust the proposed algorithm to rotation attack and other attacks, we use FMT and subbands of DWT. In this algorithm, embedding procedure of watermarking is carried out on subband of wavelet transform by FMT. For this purpose, horizontal and vertical wavelet transform subbands of logo and original images are extracted and then with applying FMT on them, embedding and extraction procedures are performed. The proposed algorithm is evaluated on various logo and images and efficiency of the proposed algorithm is reported based on various attacks and wavelet transforms. The obtained results show robustness of our algorithm encounter with many common attacks.
