An Image Forensics Tool for Copy-move Detection and Localization

We demonstrate a novel image forensics tool for copy-move detection and localization. The proposed method can determine if such tampering has occurred and which image patches are involved, and it also recovers which geometric transformation was used to perform cloning.

Detecting copy-move forgery under affine transforms for image forensics

In copy-move forgery, the copied region may be rotated and/or scaled to fit the scene better. Most of the existing methods fail when the region is subject to affine transforms. This paper presents a method for detecting this kind of image tampering based on circular pattern matching. The image is first filtered and divided into circular blocks. A rotation and scaling invariant feature is then e...

Performance evaluation of block-based copy- move image forgery detection algorithms

Copy-move forgery is a particular type of distortion where a part or portions of one image is/are copied to other parts of the same image. This type of manipulation is done to hide a particular part of the image or to copy one or more objects into the same image. There are several methods for detecting copy-move forgery, including block-based and key point-based methods. In this paper, a method...

Copy-Move Image Forgery Detection Tool

Digital images are extensively used as communication medium. Forgeries in digital image have grown to be a severe concern, owing to easy and liberated accessibility of puissant image processing tools. The literature addresses the stated issue extensively and presents solutions to them. The proposed elucidations have some commonalities in their methodologies. Nearly all of them are at variance e...

A Methodological Review on Copy-Move Forgery Detection for Image Forensics

Copy-Move forgery is the very prevalent form of image tampering. The powerful image processing tools available freely helps even the naive to tamper with images. A copy-move forgery is performed by copying a region in an image and pasting it in the same image most probably after applying some form of post-processing on the region like rotation, blurring, scaling, double JPEG compression etc. Th...
