一种Seam-insertion篡改的检测与定位方法

A Seam-insertion Forgery Detection and Localization

针对能够用于图像篡改的Seam-insertion技术,提出了一种Seam-insertion篡改识别定位算法。算法充分考虑了Seam-insertion篡改所引起的图像特征变化,提取像素点的线性特征和能量特征用于篡改的检测,并利用Seam的特性对篡改区域进行定位。实验结果表明,提出的方案能有效识别基于Seam-insertion的图像篡改,并能对篡改区域进行较为准确的定位。

A detection and localization algorithm was put forward in connection with the digital image forgery using Seam-Insertion. The algorithm in which the linear features and the energy features of pixels were extracted for the forgery detection takes full account of the change of image feature caused by Seam-Insertion operation, and by locating the tampered region using Seam characteristics. Experimental results from a large set of test images indicated the superior performance of the proposed method for both seam-insertion forgery detection and localization.
