阐述了一种利用图像内在统计特性进行图像拼接检测的方法.图像拼接检测是一个基于拼接图像特征的模式识别问题.本文通过对游程长度和图像边缘的统计特性进行分析,说明了拼接操作所引起的图像像素不相关性和不连续性.为进行拼接检测,从图像游程长度和图像边缘统计特性中提取特征量,以此特征量去训练神经网络作为最后的分类器.结果表明,由此特征量作为图像拼接检测的标准,检测结果的精确度良好.

This paper described a blind image splicing detection method based on the inherent statistical features of images. Image splicing detection is a pattern recognition problem based on the features of splicing images. In this paper, by analyzing the statistical features of run-length and the image edge, indicated the discontinuity caused by image splicing. For splicing detection, characteristics was extracted from the statistical features of image run-length and image edges, then used the characteristics to training the neural network and took the neural network as the last classifier. The final results showed that the characteristics are good for splicing detection.
