Comparative analysis of segmentation and generative models for fingerprint retrieval task
This addresses fingerprint authentication issues for biometric systems, but it is incremental as it compares existing models on a new dataset.
The paper tackled the problem of fingerprint image deterioration due to noise and damage by proposing a deep learning approach using generative and segmentation models, with the U-net model outperforming GANs in performance.
Biometric Authentication like Fingerprints has become an integral part of the modern technology for authentication and verification of users. It is pervasive in more ways than most of us are aware of. However, these fingerprint images deteriorate in quality if the fingers are dirty, wet, injured or when sensors malfunction. Therefore, extricating the original fingerprint by removing the noise and inpainting it to restructure the image is crucial for its authentication. Hence, this paper proposes a deep learning approach to address these issues using Generative (GAN) and Segmentation models. Qualitative and Quantitative comparison has been done between pix2pixGAN and cycleGAN (generative models) as well as U-net (segmentation model). To train the model, we created our own dataset NFD - Noisy Fingerprint Dataset meticulously with different backgrounds along with scratches in some images to make it more realistic and robust. In our research, the u-net model performed better than the GAN networks
