Abstract

In view of the current most based on Fourier transform domain method, its resist geometric attacks performance is very good, the embedded information is also big, but there are shearing attack ability is bad problems, and put forward a kind of based on singular value decomposition and discrete Fourier transform with the combination of double watermarking algorithm is proposed. In this scheme, first to do image singular value decomposition, and then out of decomposition of matrix DFT spectrum amplitude image watermark embedding, namely the row of molecules, to each image block DFT transform, relative to a the predefined threshold selection important coefficient, in its corresponding to the extent of the component watermark information, the weight of the original position and embedded watermark extraction preserved as a key, you will get the image with the watermark. The experimental results show that this method can achieve good image visual effect, to shear, noise, and rotated against all has good robustness.
