%X This paper proposed a new image watermarking scheme robust to geometric attacks based on image normalization and pseudo-Zernike moments.Firstly,constructed the geometrically invariant space by using image normalization.Then,obtained a significant region from the normalized image by utilizing the invariant centroid theory.Finally, embedded the watermark into the significant region by quantizing the magnitudes of the pseudo-Zernike moments. Experimental results show that the scheme is not only invisible and robust against common signals processing such as median filtering,sharpening,noise adding, JPEG compression,etc, but also robust against the geometric attacks such as affine transform,local geometric distortion, etc.
