Copy-Move Forgery Localization Using DCT With LoG Filter

Images have been used as evidence for a long time. With the introduction of digital images, there was a rise in manipulation of these images. This was a serious issue as morphed images cause misinterpretation of information available in the image. To counter image forgeries, many methodologies were developed. While some of them were computational intensive, others suffered with less accuracy. This research paper presents a novel approach to the above problem by using a LoG (Laplacian of Gaussian) filter and DCT (Discrete CosineTransform) on the image to detect a type of forgery known as Copy-Move Forgery.
