A Novel Original Streaming Video Wavelet Domain Watermarking Algorithm in Copyright Protection

摘要

In the paper, it is suggested a novel algorithm of original streaming video of wavelet domain watermarking with Independent Component Analysis (ICA) using in signal blind detection. In this algorithm, it is made up regulate model of wavelet low frequency coefficient difference in video background picked-up by ICA and quantization modulate the wavelet low frequency coefficient differences of 8 pixel blocks in one MB. This algorithm has a good stability to some common video attacks.
