| 摘 要： | 针对传统差值直方图平移算法嵌入容量偏低、多重嵌入时图像质量严重下降等缺陷,提出一种基于互补嵌入的彩色图像可逆数据隐藏算法。利用色彩分量之间的相关性和整数小波系数之间的关系减小差值,以增加差值直方图的峰值。采用双重直方图平移方法提高嵌入容量,两次嵌入过程的像素值扩展方向相反,部分像素值扩展量相互抵消,扩展量最大值为1。实...

| Abstract: | To avoid the drawback of difference histogram shifting algorithm which has lower capacity and image quality in multi-embedding,a reversible data hiding algorithm for color images based on complementary embedding is proposed in this paper.This algorithm uses the correlation of color components and the relationship between wavelet coefficients to decrease difference,so the peak of difference histogram is increased.The embedding scheme makes use of dual-histogram shifting method to increase the emb... |
