Abstract:Rotation,scaling and translation (RST) attacks can desynchronize the watermark detection so that many water-mark systems failed. A geometrically robust image watermarking strategy based on Jacobi-Fourier moments (JFMs) is proposed. The Jacobi moments of the original image are first extracted as original moments; then the watermark image is embedded into the global or local area of the original image,and the Jacobi moments of the area are extracted. When the watermarked image is not attacked,the watermark ca...
