Image Forgery Detection based on Expectation Maximization Algorithm
In this project, forgery is vital as the usage of digital pictures and images in several important places such as courts or hospitals, can misuse the technology and use it against the accused in order to get away from the crime. With the development of high-resolution digital cameras and photographs the probability of images and pictures being forged is high as the photographers have the ability to manipulate and forge the images as they desire. This can lead to a misuse of technology as forgery can lead to a major crime or difference in important and critical situations or places such as courts, hospitals, and also education system. Proposed techniques supported SIFT feature to sight the native feature of the image and effective agglomeration. This project is planned to analyze a digital image by mistreatment EM rule. A sample library of the cast and unmodified pictures, including a variety of pictures from the Associate in Nursing Multi meddling dataset.
