Abstract :
Reversible watermarking is an information hiding method, this technique retrieves the original image and the message perfectly. That is a useful tool for some specific applications such as: medical and military image systems. In this paper, a method which limits the range of threshold values is proposed. Instead of brute-force searching all threshold values in HPS method or choosing threshold values unsystematically. This method classifies and chooses a number of thresholds whose frequencies satisfy the vital capacity to gain the best imperceptibility. In addition, the proposed method puts forward a secure way of watermark. The results of the experiment on natural images and medical images show the method meets the imperceptibility and high capacity.
