| 摘 要： | 针对传统基于人类视觉系统特性的空间域与变换域相结合的水印算法中嵌入信息量小、嵌入位置定位及检测准确率低和算法运行速度慢等缺陷,提出并实现一种基于量子进化算法(QEA)的快速水印新算法。仿真实验结果表明,新算法不仅生成水印图像的速度快,而且对各种攻击具有良好的敏感性和鲁棒性。新算法在应用中有较大的灵活性,并且具有可嵌入信息容量大、运算速度快和可操作性强等特点。

| Abstract: | 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 genera... |
