| 中文摘要: |
| 针对可用于图像篡改的内容感知缩放技术，提出了一种基于概率Map图统计特征的内容感知缩放检测算法.该算法利用概率Map图以反映图像是否经过内容感知缩放操作，并利用新提出的积分投影与局部统计特征来检测篡改图像.而后利用分类器进行分类训练，从而有效识别基于内容感知缩放操作的图像篡改.实验结果显示，所提算法能够区分出原始图像与篡改图像，并具有较高的正确检测率. |
| 英文摘要: |
| In order to deal with the forged image using content-aware resizing, the content-aware resizing detection algorithm based on statistic characteristics of probability map is proposed in this paper. The method uses the probability map to reflect whether the image has been processed by content-aware resizing operation. In addition the proposed integral projection and local statistic characteristics are used to detect the tampered image. Trained by classifier, this method can then identify the content-aware resizing forgery more effectively. The experimental results reveal that the proposed detection algorithm can distinguish between original images and manipulation images with high detection accuracy. |
