Аннотация

 In this Paper, the authors state the implementation and performance analysis of digital video watermarking that use the combination of the transform domain processing of the video and fundamentals of the linear algebra. The concept of Discrete Wavelet Transform and Singular Value Decomposition has been used for the development of the proposed algorithm. The authors first applied discrete wavelet transform and then used the singular values, obtained by Singular Value Decomposition, for the insertion of the message behind the video. Two of the visual quality matrices were used for the analysis purpose.   Keywords: Digital video watermarking, discrete wavelet transform, singular value decomposition, copyright protection, visual quality matrices
