• W2217393361 abstract "In this paper, LWT(Lifting Wavelet Transform) and SVD(Singular Value Decomposition) is used to design a video watermarking technique. The video is divided into different scenes, and the last frame of each scene is selected for embedding watermark. A gray scale watermark is selected for this purpose. I have used Histogram Difference Method for dividing the video into scenes. Each RGB video frame is converted into YCbCr format, and then luminance part (Y) is taken for inserting the watermark. The LWT is applied on Y component of the video frame to decompose it into four sub parts (LL, LH, HL, HH). Then SVD is applied on the LL sub part which decomposes it into U, S, and V components. Finally watermark is also decomposed using SVD to get Sw, Uw and Vw. Then S component of the cover video frame is modified using Sw component of the watermark to embed the watermark in the cover frame. Then Inverse SVD and Inverse LWT are applied to get the final watermarked video frame. The Imperceptibility and robustness of the watermarking method is checked by applying some intentional attacks on the watermarked video frame. The results of the scheme are also compared with other existing video watermarking techniques to prove that the proposed scheme works better than other existing video watermarking schemes." @default.
