基于共生特征和集成多超球面OC-SVM的JPEG隐密分析方法
隐密分析 共生特征 多超球面
2009/8/31
隐密是指将秘密信息以不可察觉的方式隐藏于其他载体之中的技术。隐密分析的目的是检测秘密信息的存在并最终提取秘密信息。目前基于二类或多类分类器的盲隐密分析方法可有效检测已知隐密算法，但无法对未公开隐密算法的生成图像进行检测。该文提出了一种新的JPEG盲隐密分析方法，对已知或未公开隐密算法都可检测。基于共生特征和多超球面OC-SVM分类器，本方法利用能有效对载体JPEG图像的统计分布边界建模。为进一步提...

多超球面OC-SVM算法在隐秘图像检测中的应用
盲检测 图像密写分析 核K-均值聚类
2009/2/18
针对二类支持向量机分类器在图像密写分析应用中训练步骤复杂与推广性弱的缺点，把一类支持向量机（OC-SVM）引入算法，提出一种基于核的多超球面OC-SVM算法。算法利用核空间中样本特征差异突出的特性，首先对样本在核空间进行K-均值聚类，然后使用OC-SVMs对各子类训练建立多超球面分类模型，实现分类判决。实验结果表明，算法有效地实现了对隐秘图像的盲检测，提高了检测精度。
