Video watermarking scheme based on particle swarm optimization and two-dimensional mapping relationship
Feng Wang · Computer Engineering and Applications Journal · 2011
Digital video watermarking algorithms have a common problem that is how to solve the problem of the watermark capacity,robustness and non-perception of the contradiction.Based on this,a flexible algorithm is proposed for H.264/AVC video watermarking algorithm using particle swarm optimization algorithm to select the carrier location.Then the two-dimensional map relationship between the watermark information and carrier location is constructed.Simulation results show that the proposed algorithm can solve the above three contradictions,which has a strong practicality.
