A Review of Passive Image Cloning Detection Approaches

Abstract

Image Cloning is also known as copy-paste/copy-move image forgery where a fragment of the image or object is copy and paste into some other area of the same image. It is a type of image tampering with a motive either to hide the object or to falsify the information of the image. Thus it makes difficulty in the trustworthiness of the images in various real-time applications. With the easy accessibility of image manipulation software, the number of cases of image tampering is increasing. Hence there is a growing need for robust, accurate and efficient digital image forgery detection approaches. This review presented a brief discussion of various approaches for image cloning detection and will be useful for the researchers as a future direction in the area of image forensics and image forgery detection approaches implementation.
