Face Recognition in the Real World

Face recognition is a natural human skill refined over a lifetime — yet modern algorithms now surpass us even under challenging conditions. These challenges include appearance changes caused by aging, make-up, or lifestyle; variations in camera quality, viewing angles, and environmental conditions; long-range turbulence; and, importantly, demographic differences. We will also touch on scenarios where faces are captured from longer distances up to one kilometer, where factors such as optical limitations and atmospheric effects introduce unique constraints on recognition.
