With the development of digital media technology, the problem of digital product copyright protection is becoming more and more serious. The second generation of watermarking technology makes outstanding contributions to solve this problem. This article studies image edge histogram descriptor algorithm to analyze the image feature, then uses JND model which analyses characteristics of human perception to conduct watermarking embedding. The experiment results show that our watermarking algorithm has strong robustness and an acknowledgment.
