Abstract

According to several key characteristics of human vision, the paper proposes block classification watermarking algorithm based on adaptive adjustment factor. On the basis of the texture and the brightness characteristics of the image, the 8×8 block classification has been made, and then different strength adjustment factors and the embedded program have been designed according to different categories. The simulation results show that the superior performance of the algorithm enables the image to resist attack.
