提出了一种基于预测误差扩展的无位置图可逆数据隐藏方法。可逆数据隐藏方法是对图像进行一次变形,将数据隐藏到图像中,使变形后的图像与原始图像和隐藏数据完全分离。该方法仅使用一个参数提取数据;传统的基于预测误差展开的可逆数据隐藏方法需要一个位置图,而该方法在提取数据时不需要任何位置图。实验结果表明了该方法的有效性。
This paper proposes a prediction error expansionbased reversible data hiding method using no location map. Though a reversible data hiding method once distorts an image to hide data into the image, the distorted image is completely separated to the original image and the hidden data. The proposed method uses only one parameter to extract data; this method extracts data without any location map, whereas conventional prediction error expansion-based reversible data hiding method requires a location map. Experimental results show the effectiveness of the proposed method.
