    Copy-Move Forgery Detection
    (NHCE, 2022) BASIREDDY MOUNISH KUMAR REDDY: BHARATH B S: ANKIREDDY RAMA LINGESWARA REDDY
    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. There were several manipulations that could be done to an image to hide important details. Some of the most popular types of forgery include image splicing where parts of other images are superimposed on another image and Copy-Move forgery where parts of the same image are copied and moved over different regions of the same image. These types of forgeries posed a serious issue as morphed images cause misinterpretation of information available in the image. To counter these forgeries, many methodologies were developed. While some of them were computationally intensive, others suffered with less accuracy. In this project we have focused on Copy-Move forgery detection and have implemented a novel approach to localize the regions where forgeries were detected. We have modified the traditional DCT based approach and have added a filter namely LoG (Laplacian of Gaussian) to smoothen the image and generated edges. In the project, the user needs to give an image and the software developed will use DCT and LoG to detect the regions that are similar which are the regions where forgery could have taken place. The software produces an image which will mark those regions as forged. Using this software, the detection of forged images can become simpler and faster.
