— This paper presents a robust video watermarking scheme in Discrete Fourier Transform (DFT) and Sequency-ordered Complex Hadamard Transform (SCHT). The DFT and SCHT coefficients are complex and consist of both magnitude and phase and are well suited to adopt phase shift keying techniques to embed the watermark. In the proposed schemes, the phases of DFT(More)
