- Abstract:
- This paper proposes a novel method based on LPP-SIFT ( Locality Preserving Projection-Scale Invariant F’eature ’Transform ) for image copy-forgery detection, First, some steps of SF’T algorithm are used toextract key points; second, LPP is used to obtain low-dimensional feature descriptors, and then key points canbe matched by the ratio of vector angel, If mass matching key points exist in a region, the region can bejudged to have undergone copy-forged operation, Experiments demonstrate that the method can effectively de.tect forged images and locate the forged area, and this method is robust to rotation, scaling, jPEG compressionand noise addition.
