In this paper, a robust digital watermarking approach based on image normalization of invariant moment and the log-polar mapping (LPM) is proposed. By using image normalization, the invariant centroid theory and log-polar transform, the approach obtains the watermarking imbedding domain. Then the scrambling watermark image is embedded into the phase of the selected middle-frequency DFT coefficients. The experiments demonstrate that the proposed watermarking scheme is robust to a wide range of geometric attacks.
