ABSTRACT
This paper presents a robust digital watermarking algorithm for video sequence in the application of
copyrightprotection . Proposed scheme divide the video into frames.A scene change detector is used to detect the scene changed
frame.The discrete wavelet transform is used for embedding the watermark in scene change frame, using the 1 st level
decomposition i.e. LL subband.The embedding and extraction process performed using three different wavelets i.e. haar,
Daubechiesand biorthogonal. Peak signal to noise ratio, Mean square error, and structural similarity index are computed for
testing the quality of video. The proposed scheme is also tested to verify the robustness performance using normalized
correlation.Comparative performance analysis using different wavelet reveals that scene–based-watermarking shows high
imperceptibility and robustnessunder different attacks with Daubechies wavelet.
