Digital Video Disambiguation Technique Using 3-Level DWT
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2014, Vol 3, Issue 2
Abstract
Digital video watermarking technique was introduced in 1954 by Hembrooke. The watermark encodes or represents information that can defend the video, typically identifying the proprietor (source) or the deliberate recipient (destination) of the video. In this paper, we proposed a digital video watermarking technique which is based on indistinguishable frame extraction in 3-Level Discrete Wavelet Transform (DWT). In this proposed method, first host video is separated into video shots. Then from each video shot one video frame called indistinguishable frame is selected for embedding watermark. Each identical frame is decomposed into 3-level DWT, then select higher sub band coefficients to insert the watermark and the watermark are adaptively embedded to these coefficients and thus guarantee perceptual unobtrusive of watermark.
