Abstract

A rotation, scaling and translation (RST) invariant watermarking scheme using support vector machine and image moments for synchronization is proposed in this paper. Watermark is adaptively embedded in discrete wavelet transform (DWT) domain. In order to estimate RST transform parameters, support vector machine is utilized to learn image geometric pattern represented by six combined low order image moments. Watermark extraction is carried out after watermarked image has been synchronized. Experiments show that the proposed scheme can effectively resist JPEG compression, noise and geometric attacks.
