- W2385679042 abstract "For the copyright protection of digital video,a video watermarking algorithm is proposed by using the visible binary image as watermarking based on three-dimensional discrete wavelet transform(3D DWT)and HVS.First,the watermarking is preprocessed by using chaotic encryption and Arnold scrambing,and the algorithm partitions the video sequence into different scenes by using video scene segmentation method based on directional empirical mode decomposition(DEMD),some of which are selected with a key to perform 3 levels 3D DWT.Second,the watermarking is adaptively embedded into the low frequency wavelet significant coefficients by using the HVS masking characteristics of texture area and motion area.Experimental results show that the proposed algorithm is well invisible and robust to attack such as Gaussian noise,frame loss,frame average and MPEG compression." @default.
