Recaptured image detection

Webb9 mars 2024 · To make order in this vast field, we have divided the area in five sub-topics: source camera identification, recaptured image forensic, computer graphics (CG) image forensic, GAN-generated image detection, and source social network identification. Moreover, we have included the works on anti-forensics and counter anti-forensics. WebbAt last, the recaptured image was classified by the support vector machine according to the features. The experimental results showed the algorithm proposed can not only …
