An Efficient Hybrid Video Watermarking Scheme Using Discrete Wavelet Transform”

In rapid growth of network distributions of images and video, there is an imperative need for copyright protection, besides pirating. Different digital image and video watermarking schemes have been proposed to deal with this matter of ownership identification. The video watermarking schemes using discrete wavelet are transformed to keep the copyright of digital videos. The input video sequence is segmented into shots with known shots of segmentation technique. The segmented video shots are partitioned into quantity of frames considered for the embedding process. The proposed method provides the exploitation of the grayscale image as a watermark to embed into the video sequence. In this process the PSNR value calculated for each frames and select the best frame by using CS algorithm. In watermarking embedding process, segmented video data is given to the discrete wavelet transform and the encrypted image watermark data is embedded based on optimal location analysis that is carried out using ABC algorithm. The grayscale image is sliced into bit planes for analyzing each bit of the image. Afterwards, the sliced bit plane images are permuted to the watermark images which are embedded into every frame of the segmented shots with the support of the watermark embedding process. Finally, the recovery of the watermark is achieved through the aid of the watermark extraction process. The experimentation results showing the proposed video watermarking scheme provide superior results with higher accuracy.
