A wavelet based watermarking algorithm for video

Nowadays, digital contents can be copied easily because of the development of digital technology. So digital watermarking technique which aims at copyright protection of digital contents becomes more and more important, and various watermarking methods have been proposed. In this paper, a video wate...
