Enhanced digital video watermarking technique using 2-levelxs DWT

Abstract

“Watermarking” is the strategy for camouflage digital information in an exceptionally carrier signal; the shrouded information should, however does not need to be constrained for holding a reference to the carrier signal. They can also be used to verify or to recognize the house owner’s actual real identity or then again to confirm the validity or respectability of the carrier signal. It is prominently utilized for following copyright encroachments and for paper cash verification. This paper proposes an improved system of video watermarking which maximizes the normalized correlation coefficient, making the system tougher, so that they can bear common attacks. The suggested algorithm applies 2-level DWT for embedding watermark in the video, frame by frame along with a Gaussian filter, which further improves the features of suggested algorithm’s watermarked content with less deterioration of visual quality of the video. After applying the algorithm, the result shows that the suggested algorithm is sturdier against most of the common attacks with improved PSNR and imperceptibility level.
