摘要
介绍了基于数字图像隐写容量分析的最新研究成果,重点介绍了安全性限制下针对不同的隐写信道模型的隐写容量的分析和在选择给定的载体方法和失真约束条件下对一个具体图像的隐写容量计算.最后对已有的容量分析结果进行了分类,并给出了下一步研究的方向.
This paper presents the recent research of capacity analysis based on the digital images. It emphasizes the capacity analysis of steganography in the security restrictions for different models of stego - channel. Meanwhile, it computes the capacity of a specific image in a given method of cover selection and distortion restrictions. Finally, we classify the capacity analysis results given and provide some next research aspects.
