Abstract :
This paper reviews the development of digital watermarking, and proposes a FFT based blind watermarking scheme for 3D motion. The algorithm embeds a watermark into the 3D motion signals by perturbing the middle frequency coefficients of FFT domain. First, the detected signal is smoothed to get a approximation to original signal, using the theory of noise eliminating. Secondly the watermark noise is obtained by minus operation. Finally, the watermark noise is amplified in order to extract. Experimental results showed that the method was resilience to many attacks such as Gaussian White Noise, resembling, smoothing, cropping, enhancement, attenuation and rearranging.
