Special Issue Information

Dear Colleagues,

Face recognition is the most prominent biometric technique for identity authentication and is widely used in applications such as access control, time attendance, finance, law enforcement, public security, forensics, and human–computer interactions. It is a long-standing research topic, with over 50 years of research and development. Advances in deep learning and neural networks have significantly reshaped the landscape of face recognition research and applications in almost all aspects. The key engine of recent face recognition consists of network architecture evolution, a variety of loss functions, and growing face benchmarks. Even though 2D face recognition approaches reached some degree of maturity and reported very high rates of recognition across different benchmarks, the recognition performance degrades dramatically when there are large appearance variations (e.g., ageing, pose, resolution and expression) and poor environmental conditions (e.g., lighting and occlusion). In this Special Issue, we will present the history of face recognition technology, the current state-of-the-art methodologies, and future challenges existing in uncontrolled face recognition. We will specifically concentrate on the most recent large-scale databases, deep learning approaches and sophisticated loss designs in this field. Open issues will be examined and potential directions for research in facial recognition will be proposed to provide the reader with a point of reference for topics that deserve further consideration and exploration.

Face comparison/face mapping is one of the promising methods in face biometrics which needs relatively little effort compared with face identification. Various factors may be used to verify whether two faces are of the same person, among which facial landmarks are one of the most objective indicators due to the same anatomical definition for every face. This study identified major landmarks from 2D and 3D facial images of the same Korean individuals and calculated the distance between the reciprocal landmarks of two images to examine their acceptable range for identifying an individual to obtain standard values from diverse facial angles and image resolutions. Given that reference images obtained in the real-world could be from various angles and resolutions, this study created a 3D face model from multiple 2D images of different angles, and oriented the 3D model to the angle of the reference image to calculate the distance between reciprocal landmarks. In addition, we used the super-resolution method of artificial intelligence to address the inaccurate assessments that low-quality videos can yield. A portion of the process was automated for speed and convenience of face analysis. We conclude that the results of this study could provide a standard for future studies regarding face-to-face analysis to determine if different images are of the same person. Full article
