本文研究了图像盲拼接中的无缝拼接跟踪问题。图像拼接是数字蒙太奇的基本操作，而数字蒙太奇又是一种制造图像伪造的技术。虽然好的赝品可能不会留下任何被篡改的视觉线索，但它们可能会改变图像的基本统计数据。通过对照片图像的观察，我们发现了图像中的特定相关性，这些相关性可以被检测出来，并作为数字篡改的证据。由该方案得到的特征是有用的，并通过实验得到了验证
In this paper, we investigate the trace of seamless splicing for blind image splicing. Image splicing is an essential operation for digital photomontage, which in turn is a technique for creating image forgery. Although good forgeries may leave no visual clues of having been tampered with, they may, nevertheless, alter the underlying statistics of an image. Through investigating the observation of the photomontages, we find the specific correlations in the image, which can be detected and used as evidence of digital tampering. The features derived from the proposal are useful and are proved by experimentation
