Comparative Analysis of Video Watermarking Technique using 2-level DWT and 3-level DWT

Abstract: In this paper, 2-level DWT and 3-level DWT is presented and both are compared in frequency domain with quality metrics. In video watermarking, a source video is divided into number of frames and only one frame is considered. That frame is divided into 3-level DWT in these frames high bands of coefficients are selected to implant secret video/watermark logo into the frames which is applicable to all frames in a source video. This will give the assurance to invisibility for HVS. After embedding, watermarking detection is done with the same procedure. Finally comparative analysis is done with the experimental results.
