Video Watermarking Algorithm Based on Contourlet Transform and Neural Network
LI Shao-hu · Computer Knowledge and Technology · 2014
In the view of a range of issues for digital watermarking used in video copyright protection and resistance to attacks. Firstly, the original watermark image scrambling processing by Arnold transform and Hilbert curve, and then on the I frame of MPEG video using Contourlet transform watermark embedding. Finally, the use of neural networks in the extraction of the watermark blind extraction. Experimental results show that the algorithm has good invisibility and robustness.
