Multiresolution Scene Based Digital Video Watermarking

Abstract

The recent progress in the digital multimedia technologies has offered many facilities in the transmission, reproduction and manipulation of data. However, this advancement has also brought the challenge such as copyright protection for content Providers. Digital watermarking is one of the best solutions for copyright protection of multimedia data. This paper present a copyright protection method, a video watermarking technique based on the video scene segmentation and 3-level wavelet transform in which watermarks are embedded into the corresponding decomposed video. Multiresoluted watermarks are used for embedding which are obtained by pyramidal decomposition using Gaussian and laplacian pyramids. This method does not affect the perceptual quality, maintains statistical invisibility and increases the level of security to the content. The main concept is categorized to four steps watermark pre-processing, video pre-processing, embedding process and extraction process.
