Bin Xie · Video Engineering · 2012
An adaptive blind video watermarking algorithm based on low frequency coefficients in wavelet domain has been designed.The algorithm uses firstly Arnold transform to carry on scrambling encryption for the watermarking image,then the original video is decomposed the frames,and extracts the luminance component,the watermarking information is embedded into the low frequency coefficients of the luminance component three layer discrete wavelet transform,the embedding strength is adaptively selected by the low frequency coefficients.The experimental results show that the security and the imperceptibility of the watermarking are very good,it has good robustness against many kinds of attacks such as noise interference,frame deletion,frame shear,filtering,and so on.
