SPRITZ-PS: Validation of Synthetic Face Images Using a Large Dataset of Printed Documents

GAN-generated faces look challenging to distinguish from genuine human faces. As a result, because synthetic images are presently being used as profile photos for fake identities on social media, they may have serious social consequences. Iris pattern anomalies might expose GAN-generated facial photos. When photographs are printed and scanned, it becomes more difficult to distinguish between genuine and counterfeit since fraudulent images lose some of their qualities. We created a new collection of iris images from printed and scanned documents by segmenting pupils from face images to address these concerns. We employed Dlib, which provides 68 facial landmarks, and EyeCool to extract both left and right irises from a full face image to segment the iris portion. Nevertheless, due to eyelid occlusion, the extracted iris images are not entirely shaped. We have to fill missing pixels of extracted iris since there are no incomplete iris in the actual world and the incomplete image is not an adequate input to train deep neural networks. We employ the Hypergraph convolution-based image inpainting approach to do this. The detailed relationship between the iris images was determined using hypergraph convolution.
