Abstract :
In this paper, a novel blind video watermarking scheme based on discrete wavelet transform (DWT) is proposed. In this scheme, DWT is performed to each frame of the original video. Then embed watermark into some high-frequency coefficients, which are selected according to certain rules, to guarantee the perceptual quality of the watermarked video. When embedding, the quantization index modulation (QIM) algorithm is used for good robustness. The simulations show that the proposed scheme has a good performance to resist Gaussian noises, salt & pepper noises, cutting, resizing, MPEG-2 compression, frame dropping and frame changing.
