  watermark
Image adaptive RST invariant watermark using pseudo-Zernike moments
      
Rotation, scaling and translation (RST) attacks can desynchronize watermark detection, which causes failure in many watermarking systems.
      
In this paper, an image adaptive RST invariant watermark (AWPZM) is proposed by using the rotation invariant property of pseudo-Zernike moments (PZM) and oddeven quantization.
      
PZM of the original image is computed first, and then those suitable for watermark generation are selected.
      
Then, magnitudes of them are odd-even quantized to generate the watermark.

Digital watermarking has been proposed as viable solution to the need of copyright protection and other application such as information hiding,since it makes possible to identify the author,owner,distributor or authorized consumer of a document.A new technique to embed the mark signal into the image is introduced.The method operates in the frequency domain to modify the DCT coefficients of an image and then uses the characteristic of Human Visual System (HVS) to enhance the robustness of the watermark and avoid the perceptibility of human eyes.Experimental results demonstrate that the watermark is robust to most of the signal processing techniques and geometric distortions.
