Cai Qi-xian · Journal of Optoelectronics·laser · 2010
There are limitations such as smaller embedded information capacity,lower accurate rate for positioning embedded location and detection and slower running speed in traditional watermarking algorithm which combines spatial domain and transform domain based on characteristics of human visual system.A quickly-speed running watermarking algorithm based on quantum evolutionary algorithm is proposed and implemented.The simulation results show that the proposed algorithm owns not only faster watermark image generation,but also have good sensitivity and robustness for all kinds of attacks.The proposed algorithm is more flexible in application,and it can embed more information and improve the computing speed.The method can be easily operated.
