Image Forgery Detection On Cut-Paste And Copy-Move Forgeries
Abstract
Now-a-days, it is possible to manipulate an image by removing or adding important features from it without
leaving any clue of editing the original image. One can use advanced tools to digitally manipulate images to create non-
existing situations which leads to discarding the originality of images. These modifications are not visible to the naked eye.
Cut-paste and Copy-move forgeries are common image manipulations. In cut-paste forgery, a portion of another image is cut
and pasted on another image. Whereas in copy-move, part/portion of the same image is copied and moved onto the same
image. As devices like cameras are getting more and more digitized, there is an increase in the need for digital image
authentication, validation and forgery detection. To detect cut-paste forgery, we use histogram equalization detection
technique. It Detects whether the image’s contrast has been enhanced or not. For copy-move detection, up till the useful
techniques was block matching technique and key point based forgery detection method. These techniques are integrated
along with adaptive over segmentation algorithm. The adaptive over segmentation algorithm divides the image into non-
irregular blocks adaptively. Forgery regions are then detected using the forgery region extraction algorithm. Finally merged
regions are detected by applying morphological operations.
