Copy-Move Image Forgery Detection Tool
Digital images are extensively used as communication medium. Forgeries in digital image have grown to be a severe concern, owing to easy and liberated accessibility of puissant image processing tools. The literature addresses the stated issue extensively and presents solutions to them. The proposed elucidations have some commonalities in their methodologies. Nearly all of them are at variance e...
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 کاملFast Copy-Move Forgery Detection
This paper proposes a method for detecting copy-move forgery over images tampered by copy-move. To detect such forgeries, the given image is divided into overlapping blocks of equal size, feature for each block is then extracted and represented as a vector, all the extracted feature vectors are then sorted using the radix sort. The difference (shift vector) of the positions of every pair of adj...
متن کاملA Survey: Copy-Move Forgery Detection Methods
In this era due to presence of low-cost and high-resolution digital cameras, there is wide amount of digital images all over the world. Digital images play a very important role in areas like forensic investigation, insurance processing, surveillance systems, intelligence services, medical imaging and journalism. But the basic requirement to believe what we see is that the images should be auth...
متن کاملCopy-Move Image Forgery Detection in Virtual Electrostatic Field
A novel copy-move image forgery, CMIF, detection method is proposed. The proposed method presents a new approach which relies on electrostatic field theory, EFT. Solely for the purpose of reducing the dimension of a suspicious image, the proposed algorithm firstly performs discrete wavelet transform, DWT, of the suspicious image and extracts only the approximation subband. The extracted subband...
