Video watermark based on SVD spread spectrum

This paper presents a method to combine the SVD and frame synchrony in watermark. The synchrony code frame, serial number and embedding position is convenient for watermark embedding and extraction. Embedding video watermark uses part of M-series spread spectrum sequence to improve the robustness and none conjunction of video image. The experiment shows that the algorithm checks the watermark efficiently and can resist the noise attack, and can also resist the attack of frame reduction or frame addition and has very well robustness.
