| Abstract: | A zero digital watermarking image using revised Radon invariant moments is proposed. Firstly calculating Radon invariant moments of original image and using the Radon invariant moments of original image to construct zero water marking system. Then correcting the Radon invariant moments of test image by related coefficient of two images. Finally the detection of watermarking system is achieved by calculating the Radon revised invariant moments. The proposed method not only has the whole performance but also can resist to commonplace signal processing. Simulation experiments demonstrate the proposed method is better robust than traditional Radon invariant moments in noise attacking. |
