- 由于图像在经过一次 JPEG 压缩和双重 JPEG 压缩之后其 DCT 系数具有一定的相关性，通过对这种相关性进行分析，提出了一种基于 JPEG 图像双重压缩特性的图像篡改检测算法，并用此算法检测图像是否经过篡改和定位篡改区域。 -Since the image after a first JPEG compression JPEG compression and double its DCT coefficients having some relevance, by this corre

PCA
- PCA（Principal Component Analysis）不仅仅是对高维数据进行降维，更重要的是经过降维去除了噪声，发现了数据中的模式。 PCA把原先的n个特征用数目更少的m个特征取代，新特征是旧特征的线性组合，这些线性组合最大化样本方差，尽量使新的m个特征互不相关。从旧特征到新特征的映射捕获数据中的固有变异性。-PCA (Principal Component Analysis) is not just for high-dimensional data dimensiona
