Face morphing detection in the presence of printing/scanning and heterogeneous image sources
Face morphing represents nowadays a big security threat in the context of
electronic identity documents as well as an interesting challenge for
researchers in the field of face recognition. Despite of the good performance
obtained by state-of-the-art approaches on digital images, no satisfactory
solutions have been identified so far to deal with cross-database testing and
printed-scanned images (typically used in many countries for document issuing).
In this work, novel approaches are proposed to train Deep Neural Networks for
morphing detection: in particular generation of simulated printed-scanned
images together with other data augmentation strategies and pre-training on
large face recognition datasets, allowed to reach state-of-the-art accuracy on
challenging datasets from heterogeneous image sources
Palmprint Gender Classification Using Deep Learning Methods
Gender identification is an important technique that can improve the performance of authentication systems by reducing searching space and speeding up the matching process. Several biometric traits have been used to ascertain human gender. Among them, the human palmprint possesses several discriminating features such as principal-lines, wrinkles, ridges, and minutiae features and that offer cues for gender identification. The goal of this work is to develop novel deep-learning techniques to determine gender from palmprint images. PolyU and CASIA palmprint databases with 90,000 and 5502 images respectively were used for training and testing purposes in this research. After ROI extraction and data augmentation were performed, various convolutional and deep learning-based classification approaches were empirically designed, optimized, and tested. Results of gender classification as high as 94.87% were achieved on the PolyU palmprint database and 90.70% accuracy on the CASIA palmprint database. Optimal performance was achieved by combining two different pre-trained and fine-tuned deep CNNs (VGGNet and DenseNet) through score level average fusion. In addition, Gradient-weighted Class Activation Mapping (Grad-CAM) was also implemented to ascertain which specific regions of the palmprint are most discriminative for gender classification
