| 摘 要： | 给出了一种JPEG域基于离散余弦变换(DCT)系数多方向相关性的图像信息隐藏盲检测方法。首先利用DCT系数多方向相关性构造差值彼邻相关矩阵，然后利用此矩阵提取48维特征向量，最后使用支持向量机(SVM)区分载体、载密图像。该方法应用于6种典型的JPEG图像隐写算法，实验结果表明，该方法对这些隐写算法都能够进行比较可靠的检测。

| Abstract: | A blind steganalysis method based on multi-orientation correlation of Discrete Cosine Transform(DCT)coefficient was presented.This method first applied multi-directional correlation of DCT coefficient to construct difference neighboring correlation matrix,then extracted 48 dimensional features for each image,finally Support Vector Machine(SVM)was used to classify the cover and stego images.A series of experiments were performed on 6 kinds of typical steganography of different embedding ratio.The results sho... |
