Abstract :
By improving existing technology used in noise sensitivity, a novel adaptive blind watermarking algorithm is proposed. The embedding procedure operates adaptively in the domain of intermediate coefficients, according to the noise sensitivity. Robustness of it on selected attacks like Gaussian noise, median filtering, JPEG compression and cropping is tested. In addition, the perceptual transparency has been improved as well. Furthermore, the watermark can be detected without the original image.
