Video Digital Watermarking Algorithm Based on Chaotic Sequences and Wavelet Lifting
摘要
Abstract
In this paper, the scrambled watermark is embedded in DCT coefficients of low-frequency sub image with the Brightness Component of original color image after lifting wavelet transformation. Before embedding the watermark, the image confusion method is used to eliminate the space correlation of the pixels and improvs the security and robustness. The results showed that the algorithm is easy to carry out with the real-time reqest of video watermarking.关键词
