| 中文摘要: |
| 为了进一步提高隐写分析算法的检测精度,提出 了一种基于成对采样选择性集成的隐写分析算法。 从集成分类的特点和隐写分析的特殊性出发,分析了类内以及类间样本之间的联系,研究了 4种不同的采样策 略,并基于成对采样策略构建选择性集成分类器用于隐写分析。实验表明,不同采样策略能 不同程度地影响隐 写分析的检测性能；与现有隐写分析方法相比,本文算法能明显降低隐写分析系统的检测错 误率(BER)。 |
| 英文摘要: |
| A novel steganalysis algorithm based on paired sampling and selective ensemble is proposed to improve detection accuracy of steganalysis.Considering the characteristics of ense mble classification and the particularity of steganalysis,we analyze the relation between two classes of s amples and the link among samples of the same class,put forward four different sampling strategies,and build selective ensemble classifier based on paired sampling strategy for steganalysis．Experimental results showed that different s ampling strategies could influence the performance of detection in steganalysis to some extent.Compared with the exist ing methods in steganalysis,the proposed method can significantly reduce the error rate in detection performance of steganalysis system． |
