Copy-move forgery detection via texture description [PDF]

Proceedings of the 2nd ACM workshop on Multimedia in forensics, security and intelligence, 2010
Copy-move forgery is one of the most common type of tampering in digital images. Copy-moves are parts of the image that are copied and pasted onto another part of the same image. Detection methods in general use block-matching methods, which first divide the image into overlapping blocks and then extract features from each block, assuming similar ...

SMDAF: A novel keypoint based method for copy‐move forgery detection

IET Image Processing, 2022
Copy–move forgery poses a significant threat to social life and has aroused much attention in recent years. Although many copy‐move forgery detection (CMFD) methods have been proposed, the most existing CMFD methods are short of adaptability in detecting

Copy-Move Forgery Verification in Images Using Local Feature Extractors and Optimized Classifiers

Big Data Mining and Analytics, 2023
Passive image forgery detection methods that identify forgeries without prior knowledge have become a key research focus. In copy-move forgery, the assailant intends to hide a portion of an image by pasting other portions of the same image. The detection

Copy Move Forgery Detection with Quadtree Decomposition Segmentation

2020 43rd International Conference on Telecommunications and Signal Processing (TSP), 2020
The increasing usage of digital images and the wide availability of easy-to-use image editors have made the authenticity of images questionable. Copy-move is one of the most applied forgery types. The keypoint-based copy move forgery detection methods in the literature cannot detect forgeries with smooth regions. In this paper to overcome this problem,
