摘要：Image splicing is the most fundamental step of photomontage. In this paper, we propose an efficient blind digital forensics method for image splicing localization. In our method, the demosaicing is used for estimating the natural counterpart of spliced image, which is compared with the test image to expose the abrupt edges along the spliced region. According to the smoothness comparison results, we obtain a binary image to illustrate the localization of the splicing. To evaluate the performance of our method, we apply this approach to DVMM uncompressed spliced image database, and the experimental results indicate the effectiveness on splicing localization. ? 2012 Springer-Verlag.
