A video watermarking algorithm based on three dimensional wavelet transform
An effective video watermarking algorithm is proposed in this paper. We use an visible binary image as the watermark. The watermarking procedure is based on the three dimensional discrete wavelet transform(3D-DWT). After the one level 3DDWT coefficients are blocked, the watermark is embedded into the appropriate 3D-DWT coefficients considering the robustness and the invisibility. The experimental results demonstrate that the watermarking method has good invisibility and has strong robustness against some common attacks, such as compression of MPEG-2, noise attack, median filter. The scheme is less complex and has smaller calculation deal, so it can meet the real-time requirement.
