A Copy-Move Forgery Detection Method for VDR Image

Abstract

The authenticity of VDR images is facing a severe test due to advanced image processing technology. Aiming at the issue of using copy-move forgery method to cover up the truth of marine accidents in VDR images, a VDR image copy-move blind forensics method is proposed. In the proposed work, the images are decomposed by Bi-dimensional Empirical Mode Decomposition (BEMD), and SURF algorithm is employed to obtain feature point descriptor. Comparisons with the prevailing methods show that the proposed method improves the detection accuracy. Furthermore, it is invariant to any rotation or scaling in the copy-move region.
