摘要
Abstract
According to Shamir (T ,N ) threshold scheme ,a robust video watermarking algorithm is proposed .In the generated watermarking ,using the (N ,N) threshold scheme ,the image watermarking information compression to the origi‐nal information after the 1/N of watermark embedding can greatly reduce the magnitude of the embedded watermarking . When embedding watermarking ,characteristics of intermediate frequency coefficient after using DCT transform ,embedding the watermarking into the Ⅰ frame improve the robustness of the watermarking .The experimental results show that the new algorithm can resist salt and pepper noise ,Gaussian noise ,re‐coding compression and other many kinds of attacks ,showing better robustness .关键词
