Comprehensive study of different types image forgeries g k s gaharwar1, 2, prof v v nath3, image forgery means manipulating digital image to hide some important and key information from the image images at the time of image acquisition or in processing stage and digital signatures embed some secondary. With the advancement of the digital image processing software and editing tools, a digital image can be easily manipulated the detection of image manipulation is very important because an image can be used as legal evidence, in forensics investigations, and in many other fields. Copy-move forgery is one of the common image forgery techniques the attackers copy a part of an image itself and, with the purpose of disguising some details, paste it to another part of the same image unlike coping from different source images, coping from the same and different post image processing as shown in figure 1, (a) is an.

Typical image processing tools, copy-move forgery is one of the most commonly used methods the copy- image forgery is to hide certain details or to duplicate some aspects of an image [3] generally, copy-move forgery detection techniques can be classified into two. This section describes the proposed image forgery detection using adaptive over-segmentation [10] in details fig 1 shows the framework of the proposed method for image forgery detection firstly, the adaptive over-segmentation method is proposed to divide the input image into non- against common image processing operations such as. Segmentation-based image copy-move forgery detection scheme an image with copy-move forgery (cmf) contains at least a couple of regions whose contents are identical cmf may be performed by a forger aiming either to cover the truth or to enhance the visual effect of the image.
