%X In order to improve the ability against rotation attack of zero digital image watermarking method,this paper proposed a method based on Contourlet transform against rotation caused by distortion,Log-Polar Mapping(LPM) was used to transform rotation problem in Castesian coordinate to translation property in LPM coordinate.After translation,an exhaustive search was adopted to detect test whether image involves watermarking or not.The experimental results demonstrate that the proposed method can obtain better ...
