Video watermarking algorithm based on moving object detection

To improve the robustness of video watermarking,a video watermarking algorithm based on moving object detection was proposed.The paper made use of the temporal differencing algorithm to extract and sign the moving targets in the video image sequences,and then,achieved watermark embedding and extraction processes by Singular Value Decomposition(SVD) method.In the simulation,the Peak Signal-to-Noise Ratio(PSNR) was calculated to show that this scheme has a great invisibility and concealment,the strimark software was used to geometricly attack on watermarked image,the correlation coefficient was analyzed to prove that this algorithm has a great robustness.
