Reversible data hiding scheme based on asymmetric histogram modification
using two different forecast methods to calculate the prediction error of the original image
two asymmetric prediction error distribution histogram generated
when making secret information embedded respectively on two asymmetric prediction error distribution histogram in the opposite direction of translation ways.Compared with the traditional scheme
the improved scheme can play better to the complementary advantages of embedding strategy
make as many pixels pixel values compensation occur
further protecting the secret image quality.
