Fingerprint Identity Preserving Generative Adversarial Networks
Kačur, Ján ; Juránek, Roman (oponent) ; Špaňhel, Jakub (vedoucí práce)
This thesis focuses on generating latent fingerprints using Generative adversarial networks. The main objective is to generate multiple latent fingerprints from the clean fingerprint, with the same identity. The identity and the style should also be controllable separately. The chosen approach is based on AugNet model. Designed algorithm generates latent fingerprints from clean binarized fingerprint, and a random vector encoding distortions, i.e style. In the generator, AdaIN blocks are used to incorporate distortions into the input fingerprint. Various training algorithms are tested, with WGAN-GP performing the best. Individual models are compared using a combination of FID, and Rank-1 accuracy on matching generated images to original input binarized fingerprints. Best performing models are selected as a Pareto optimal combinations of these 2 metrics.
