Detection of Copy-Move Forgery in Digital Images Using Scale Invariant Feature Transform Algorithm and the Spearman Relationship
Increased popularity of digital media and image editing software has led to the spread of multimedia content forgery for various purposes. Undoubtedly, law and forensic medicine experts require trustworthy and non-forged images to enforce rights. Copy-move forgery is the most common type of manipulation of digital images. Copy-move forgery is used to hide an area of the image or to repeat a por...
متن کاملPerformance 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...
متن کاملStudy and Analysis of Copy-Move Forgery Detection in Digital Image: A Review
---------------------------------------------------------------------***--------------------------------------------------------------------Abstract In today's digital age, Digital image forgery becomes a common information falsification trend. This is generally done due to the largely available contemporary editing software and superior digital cameras. Authenticity of images becomes a more im...
متن کاملForgery Detection Using Adaptive Over - Segmentation and Feature Point Matching
Abstract—A novel copy-move forgery detection scheme using adaptive over-segmentation and feature point matching is proposed in this paper. The proposed scheme integrates both block-based and keypoint-based forgery detection methods. First, the proposed Adaptive Over-Segmentation algorithm segments the host image into non-overlapping and irregular blocks adaptively. Then, the feature points ar...
متن کاملNon-Overlapping Block-based Parametric Forgery Detection Model
Modification of a digital image by adding or removing some of its elements using a wide variety of image processing tools results in image forgery. As a result authentication of originality of a digital image is becoming a challenging task. Copy-paste forgery is one of the forgeries belonging to context based forgery. Copy-Paste Forgery Detection (CPFD) aims at finding regions that have been co...
متن کاملCopy-Move Forgery Detection in Digital Images by Reduced Features Ovelapping Block-Based Algorithm
Digital image forgery is one of the problems that, besides many benefits, appears with widespread use of digital images in all areas of life. Unfortunately, with rapidly developing and increasingly more powerful hardware and software, not only is digital photography manipulation for legitimate goals easier, but also for the forgery. One well-known forgery of digital images is the so-called copy...
