An Evaluation of Digital Image Forgery Detection Approaches
This addresses the problem of verifying image integrity for legal, forensic, and other fields, but it is incremental as it surveys existing methods.
The paper reviews various image forgery detection techniques, focusing on pixel-based methods to verify digital image authenticity without prior knowledge of the original.
With the headway of the advanced image handling software and altering tools, a computerized picture can be effectively controlled. The identification of image manipulation is vital in light of the fact that an image can be utilized as legitimate confirmation, in crime scene investigation, and in numerous different fields. The image forgery detection techniques intend to confirm the credibility of computerized pictures with no prior information about the original image. There are numerous routes for altering a picture, for example, resampling, splicing, and copy-move. In this paper, we have examined different type of image forgery and their detection techniques; mainly we focused on pixel based image forgery detection techniques.
