Abstract

A new watermarking method for color video using a nonlinear digital filter is proposed. This method is based on Haitsma and Zhao's methods which embed watermark signals into the luminance mean series, but newly introduce a nonlinear digital filter, named as a component separating filter (CS filter), in the detecting process to improve the detecting performance. The CS filter can effectively extract the small-amplitude watermark signals on the mean series without being affected by the abrupt shot change. Moreover, it is shown that higher performance is realized by embedding into the color difference signal instead of the luminance. Computer simulations verify its performance.
