摘要：

The image gradient prediction method is applied to select and predict the trend of each pixel's gradient. The, the pixel's value is predicted according to the gradient and adjacent pixels. The use of the reversible data hiding algorithm based on prediction error can effectively reduce the prediction error and improve the hiding capacity. Moreover, in the hiding process, the embedding rule is adjusted to reduce the distortion to the host image. Experimental results show that the proposed algorithm can achieve a very embedding rate and has good concealment. © 2016, Editorial Board of Jilin University. All right reserved.
