Nonoverlapping Blocks Based Copy-Move Forgery Detection

Security and Communication Networks, 2018
In order to solve the problem of high computational complexity in block-based methods for copy-move forgery detection, we divide image into texture part and smooth part to deal with them separately. Keypoints are extracted and matched in texture regions.

Copy-Move Forgery Detection Using Deep Learning

, 2021
Due to the number of image editing tools available online, image tampering has been easy to execute. The quality of these tools has led these tamperings to steer clear from the naked eye. One such tampering method is called the Copy-Move tampering where a region of the image is copied and pasted elsewhere in the image.
