Polar co-ordinates shape adaptive discrete transform-based watermarking scheme for arbitrarily-shaped object
No full textA new watermarking scheme for arbitrarily-shaped image is proposed, Using co-ordinate's conversion to log-polar and polar co-ordinates shape adaptive discrete transform (PSADT). the proposed watermarking method can be applied to any arbitrarily-shaped image such as MPEG-4 VOP and is much more robust to geometrical attacks than conventional ones
