Reversible data hiding using prediction error difference expansion without location map
无定位图的预测误差差值扩展可逆数据隐藏*

This paper proposed a reversible data hiding algorithm for color images using prediction error difference expansion.To avoid the drawback of Tian's algorithm which must embed a location map and the quality decline of stego-images from excessive modulation to pixels,this algorithm using correlation of color components to decrease difference and disperse smaller expansion to two components,and improved histogram shifting technique to improve the quality of stego images,the embedding pixels was determined with...
