Special Issue Information

Dear Colleagues,

Currently, we are witnesses of the fourth industrial revolution, also known as Industry 4.0 in Europe, Society 5.0 in Japan and the Industrial Internet of Things (IIT) in the USA. The main characteristics of this new living model are the massive interaction of humans with machines (smartphones, computers, social robots, etc.) and the generation, storing and processing of big data using A.I. algorithms and the Internet of Things (IoT).

In this context, there is a continuously increasing need to identify humans and entities in general, by analyzing their patterns. For example, in the coming years, humans will interact with ATM machines without using debit cards but with their biometrics.

Although significant progress has been reported recently in the field of biometrics by incorporating deep learning models, the task of identifying someone under varying conditions is still open. For example, human identification in the wild or using only a few samples of data are cases that merit more attention and research towards better analysis of the patterns describing the identities.

This Special Issue aims to summarize the recent advances in extracting and analyzing patterns that are able to identify the owner of them. Topics may include but are not limited to:

  • Face recognition/verification;
  • Iris recognition/verification;
  • Fingerprint recognition/verification;
  • Ear recognition/verification;
  • Vein recognition/verification;
  • Gait recognition/verification;
  • EEG recognition/verification;
  • Behavioral biometrics;
  • Multimodal and adaptive biometric systems;
  • Adversarial machine learning for biometric systems;
  • Feature extraction;
  • Storing and processing big biometric data;
  • New biometric systems architectures;
  • New benchmark datasets;
  • New applications.

In this paper, we propose a novel loss function for deep face recognition, called the additive orthant loss (Orthant loss), which can be combined for softmax-based loss functions to improve the feature-discriminative capability. The Orthant loss makes features away from the origin using the rescaled softplus function and an additive margin. Additionally, the Orthant loss compresses feature spaces by mapping features to an orthant of each class using element-wise operation and 1-bit quantization. As a consequence, the Orthant loss improves the inter-class separabilty and the intra-class compactness. We empirically show that the ArcFace combined with the Orthant loss further compresses and moves the feature spaces farther away from the origin compared to the original ArcFace. Experimental results show that the new combined loss has the most improved accuracy on CFP-FP, AgeDB-30, and MegaFace testing datasets, among some of the latest loss functions. Full article
