An algorithm for multiple video watermarks based on ICA and DWT
Fuli Wang · Information technology newsletter · 2011
A new video watermarking algorithm is proposed,based independent component analysis(ICA) and discrete wavelet transform(DWT).This algorithm used binary image and gray image,scrambled them,then got two images aliasing with ICA,selected one of them used to watermarking,another as key,in order to increase the security of watermarking.The watermarking is embedded in the original video of DWT low frequency sub-band coefficient with ICA,so as to realize the blind watermarking signal detection,considering the frame clipping,frame,lost frame average and MPEG coding has good robustness.
