Speech titleRole of GAN in Image Forgery Detection


Abstract:

DeepFake is a GAN-based technology that can swap out a person's identity with that of another. GANs (Generative Adversarial Networks) create incredibly realistic faces that are difficult to identify by naked eyes. A photo-realistic image may now be readily created from a random vector by the fast advancement of generative adversarial networks. It is proved as a game changer as it outperforms in feature and expression learning. It's become a hot topic for researchers to figure out if a given facial photograph is real or fake especially circulated in social media. As a result, detecting the GAN-generated deepfake images or videos is becoming a crucial task to be identified. This paper primarily presented different deepfake manipulation techniques, an overview of GAN models used to implement deepfakes, as well as different limitations of GAN model based on different evaluation parameters. Also, a GAN model is implemented using Deep convolution neural networks. A closure of its generated images with successive iterations is also discussed. GAN outputs are analyzed using different accuracy curves with focus on mode collapse and convergence as major evaluating parameters.
