Abstract
Copy-move forgery, or region-duplication, is a common type of digital image tampering. This paper presents a novel approach to detect copy-move forgery even if rotation and/or scaling took place before copying. The image under test is divided into fixed-size blocks, and log-polar Fourier transform (LPFT) is performed on the inscribed circles of these blocks. Similarity in the LPFT between different patches provides an indication of the copy-move operation. Experimental results show efficacy of the proposed method.
