Abstract

Using the stability of the low-frequency components in 1D-DWT(1-dimension discrete wavelet transform), a blind video watermarking scheme is proposed in the paper. The watermark is embedded in the blocked low-frequency image by adjusting the average pixel value of each block. The watermark is detected by the interval which the average pixel value of each block belongs to. The experimental results demonstrate that the watermarking method has strong robustness against some common attacks, such as compression of MPEG-2, noise attack, frame exchanging. The scheme is less complex and has smaller calculation deal, so it can meet the real-time requirement.
