Face Recognition Across the Imaging Spectrum : Springer : 9789819720583 : 9819720583 : 04 Nov 2024 : Embark on a journey through the recent groundbreaking developments in face recognition (FR) systems with our second edition. Initially designed for controlled conditions, FR systems have evolved to conquer real-world challenges, adapting to low-light scenarios and extended distances. Our book delves into the transformation brought about by advancements in imaging sensors and cost-effective infrared (IR) cameras, exploring intensified near-infrared (NIR), shortwave IR (SWIR), middle-wave IR (MWIR), and long-wave IR (LWIR) imagery. This edition caters to the burgeoning interest in FR technologies, aligning with recent strides in computer vision, pattern recognition, and biometric analysis. Tailored for biometrics researchers, practitioners, and students, it addresses the critical need for FR algorithms in operational environments. Our book encompasses three comprehensive sections: (a) Fac
