Abstract:
This paper proposed a new robust watermarking scheme using scale-invariant feature transform (SIFT) for the discrete wavelet transform (DWT) domain. In the proposed scheme, some SIFT feature regions are first determined in the original image. Then, these SIFT feature regions are transformed by using DWT transformation to generate the DWT coefficients, which is used to carry the watermark. In the receiver side, the watermark can be extracted correctly from the watermarked image. Experimental results show that the proposed scheme is withdraw under various attacks. In addition, in comparison with some exiting schemes, our proposed scheme obtains the stronger robustness than these schemes in regards with robustness and the visual quality.
