Embedding intensity of the video watermark will directly affect robustness and non-perception of the watermark. Great embedding intensity will affect non-perception of the watermark, and small embedding intensity will affect robustness of the watermark. In order to make robustness and non-perception achieve the best integrated optimization. This paper proposes a scheme of digital video watermark algorithm based on particle swarm optimization, it selects embedding intensity of watermark by particle swarm optimization (PSO), watermark information is embedded in the middle frequency coefficients of discrete wavelet transform (DWT) by multiplication embedding algorithm, The simulation results show that, the algorithm can better reflect watermark robustness and non-perception, and has better practicability
