This paper presents a novel robust image watermarking scheme for resisting geometric attacks. In the proposed scheme, watermark synchronization is first achieved by the local circular regions, which can be generated using the scale-invariant feature transform (SIFT). Then the watermark is embedded into each local region in spatial domain by odd-even quantization. In the decoder, the watermark can be extracted using the proposed odd-even detector. Simulations and comparisons have demonstrated the effectiveness of our scheme.
