| 摘 要： | 对图像的高阶统计量进行研究,首先利用离散余弦变换(DCT)域共生矩阵、空域边界梯度能量和空域图像子块的虚特征值分解等对基于模型(MB)隐写带来的变化进行描述,然后利用支持向量机(SVM)设计了MB隐写分析算法.实验结果表明,算法在保持低虚警率的同时具有较高的检出率.

| Abstract: | A new steganalysis algorithm on model-based(MB) steganography is proposed after researching the high order statistics of images.The difference,imported by MB steganography is described by the co-occurrence discrete cosine transform(DCT) matrix,the boundary gradient energy in airspace and the imaginary eigenvalue decomposition.The MB steganography is detected using all of the features and support vector machine.Experiments show that this algorithm has a high accuracy rate of detection with a low false detection rate. |
