Copy-move forgery detection using ASIFT

2016 1st India International Conference on Information Processing (IICIP), 2016
Detecting forgeries in images especially those involved in Copy-Move forgery could become a challenging prospect in the acreage of image forensics. The significance of detecting such forgeries comes to light, given the rise of such malpractices. Now we will see a approach using ASIFT which is planned to expose regions which have been copied and then ...

New Copy-Move Forgery Detection Algorithm

2019 International Russian Automation Conference (RusAutoCon), 2019
In the era of digitization, the digital image plays a documentary role and consolidates a belief. Therefore, the image has to be trustworthy as important as the belief it influences. However, the digital world also came accompanied with the easiness of image manipulation for fun or forgery by available simple or professional image editing programs or ...

Copy-Move Forgery Detection Using DyWT

International Journal of Multimedia Data Engineering and Management, 2017
In this paper, we proposed a passive method for copy-move region duplication detection using dyadic wavelet transform (DyWT). DyWT is better than discrete wavelet transform (DWT) for data analysis as it is shift invariant. Initially we decompose the input image into approximation (LL1) and detail (HH1) sub-bands.

Rotation robust detection of copy-move forgery

2010 IEEE International Conference on Image Processing, 2010
Copy-move tampering is a common type of image synthesizing, where a part of an image is copied and pasted to another place to add or remove an object. In this paper, an efficient algorithm based on the Fourier-Mellin Transform is proposed with features extracted along radius direction. Also, to reduce computational cost, a link processing is introduced

Copy-move forgery detection based on PatchMatch

2014 IEEE International Conference on Image Processing (ICIP), 2014
In this work we propose a new algorithm for copy-move forgery detection and localization, based on the fast computation of a dense nearest-neighbor field. To this end, we use PatchMatch, an iterative randomized algorithm for nearest-neighbor search, which exploits the regularity of natural images to converge very rapidly to a near-optimal and smooth ...

Copy-move forgery detection using lexicographical sort

2016 Fourth International Conference on Parallel, Distributed and Grid Computing (PDGC), 2016
Copy-move forgery is one of the widely used forgery technique to alter digital image to conceal its originality. To testify the originality of an image, many detection techniques have been proposed and it is a very popular research field these days. Here we have presented a detection method based on discrete cosine transform (DCT) using lexicographical

Accurate And Efficient Copy-Move Forgery Detection

2019 9th International Conference on Advances in Computing and Communication (ICACC), 2019
Today, due to the development of image processing applications like GIMP and Photoshop, forging of digital images with the absence of any trace is not at all difficult. Therefore crucial validation of content in a digital image is essential. Among the many prevailing forgery techniques, the copy-move forgery is recurrently occurring and it is easily ...

Passive copy-move forgery detection in videos

2014 International Conference on Computer and Communication Technology (ICCCT), 2014
Due to evolution of prevalent sophisticated digital video editing software it has become easier to forge any video. Copy-Move forgery is a special kind of video forgery technique, in which copy-move of the frame region is performed in intra frame or inter frames.

Copy-Move Forgery Detection Using Cellular Automata

2014
Thanks to the availability of many sophisticated image processing tools, digital image forgery is prevalent nowadays. One of the common methods is copymove forgery (CMF), where part of an image is copied to another location in the same image. Detection of copy-move forgery has been widely researched recently, and many different solutions have been ...

Efficient Dense-Field Copy–Move Forgery Detection

IEEE Transactions on Information Forensics and Security, 2015
We propose a new algorithm for the accurate detection and localization of copy–move forgeries, based on rotation-invariant features computed densely on the image. Dense-field techniques proposed in the literature guarantee a superior performance with respect to their keypoint-based counterparts, at the price of a much higher processing time, mostly due
