Several research studies have established the uniqueness and stability of finger knuckle patterns. Its formation has been linked to genetic factors during the gestation stage. Matching of knuckle creases and patterns is now widely employed to establish the identity of suspects for criminal prosecutions, especially when knuckle patterns are the only piece of evidence available for such investigations. However, such pattern matching adopted by law enforcement personnel is largely manual and, therefore, very time-consuming. It is almost impossible to detect the presence of knuckle patterns and to establish a match, on a real-time basis from a large number of videos and images that are often present in suspects’ mobile phones and laptops. Therefore, completely automated capabilities to detect the presence of knuckle patterns, and to match them from a gallery, are highly sought. This talk will discuss on such challenges and advances for finger knuckle identification in the wild.
