| 摘 要： | 提出数据挖掘在图像信息隐写分析中的应用。首先计算原始图像和隐写图像在通用图像质量指标下的失真测度,然后利用数据挖掘技术建立一个预测模型,完成失真测度到已知隐写概率的映射,模型的输出即为预测隐写概率。实验结果表明,使用该方法得到的预测隐写概率和已知隐写概率的相关度,当使用训练样本时达到0.951以上,使用测试样本时达到0.943以上,达到了很好的预测效果。

| Abstract: | A method was proposed that applied statistical data mining to steganalysis of im- ages.First the distortion measurement between the original and steganography images was com- puted in a universal image quality index,followed by a forcast model constructed by data mining to accomplish the mapping from the distortion measures to the known steganalysis probability. The output of the model was the forecastable steganalysis probability.The simulation shows that the correlation degree between the known steganalys... |
