Round Descriptor Based on SIFT Operator Copy and Paste Forensics

Abstract:

Powerful digital cameras and image processing software, so that the image of tampering counterfeit technology is developing rapidly, the role of digital images to verify the authenticity and the beginning of forensics technology will become more important. For the most common digital image tampering copy and paste operation, this paper presents a round-based SIFT descriptor operator forensic image copy and paste algorithm that extracts the image to be detected circular feature vector descriptor, and using feature vectors copy and paste the image matching to detect and locate the area. Experiments show that the method of image rotation, zoom, blur, noise and other image processing operations are robust, able to quickly and effectively detect tampering in digital images traces copy and paste operations, and is able to copy and paste the region for accurate positioning.
