Video Watermarking Based on DWT-SVD
Yubo Zhang · Science Technology and Engineering · 2010
The digital video watermarking algorithm combined DWT and SVD is proposed.The video is selected with NCG greater than the threshold as the embedded frame.Each selected frame is decomposed by DWT,then the resultant mid-frequency coefficients are decomposed by SVD.The singular values is modified to accomplish the embedding of the binary watermark.Afterwards the side information of partial original video is exploited to realize the semi-blind extraction of watermark.Simulation results show that the proposed algorithm has much transparency and can resist common attacks such as filtering,JPEG compression,cropping etc.
