      Image watermarking algorithm based on structure tensor

      摘要:
      随着多媒体技术的快速发展,多媒体信息产品的安全性问题越来越受到关注.数字水印技术作为解决多媒体产品安全问题的关键技术已成为当前研究的热点.文中提出了一种基于结构张量的数字图像水印算法.实验结果表明,该算法具有较好的不可见性,计算复杂度较低,而且在提取水印时,利用相关检测,具有较高的准确率.
      Abstract:
      With the rapid development of multimedia technology,the security problems of multimedia information product are paid more and more attention.Currently,digital watermarking technology as one of key technologies to solve the above-mentioned problem has become a hot topic.This paper presents a digital image watermarking algorithm based on structure tensor.The experimental results show that the proposed method has good imperceptibility performance and lower computational complexity.Moreover,its detect accuracy is very good.
