Abstract :
The proposed method of the paper reduces the number of iterative steps in previous methods by balancing the required capacity histogram of prediction errors and determining two or four thresholds. In addition, other methods will shift a constant for embedding information bits if these bits are “1”. The histogram of prediction error will not change for embedding information bits if these bits are “0”. Hence, the method chooses the way which will shift if the information bits are “0” or “1” for the lowest distortion. The experimental results show this method is efficient the imperceptibility, capacity and less iterative steps than other´s.
