New DWT dynamic video watermarking algorithm
Hongyan Sun · Journal of Jilin University · 2013
A new of video dynamic watermarking algorithm based on DWT was proposed,parity frame of the video was separated from the video,the low frequency component after the decomposition of the secondary DWT of the parity frame was used to complete dynamic embedded watermarking frame,watermarking was recoveried by selecting integer coefficients to expand the selection of the watermarking information.Simulation results show that the algorithm can recover the watermarking better from embedded vodeo under resisting the attack of lossy compression and filtering.The concealment of the video is enhanced while the video robustness is maintained.
