ABSTRACT:
A dynamic wavelet feature-based watermark for use with digital video. Scene change detection separates digital data into one or more scenes, wherein each of the scenes is comprised of one or more frames. A temporal wavelet transformation decomposes the frames of each scene into dynamic frames and static frames. The static frames of each scene are subjected to a spatial wavelet transformation, so that the watermark can be cast into middle frequency sub-bands resulting therefrom. Polyphase-based feature selection or local block-based feature selection is used to select one or more features. The watermark is cast into the selected features by means of either (1) a comparison of energy in polyphase transform components of the selected feature, or (2) a change in value of blocked wavelet coefficients of the selected feature.
