Sobre IBD

Nel mondo elettronico moderno sono stati sviluppati diversi tipi di sistemi biometrici. Il sistema di riconoscimento delle impronte digitali è una delle tecnologie emergenti grazie alla sua stabilità, alle sue caratteristiche uniche, al dispositivo di acquisizione a basso prezzo e alla velocità di esecuzione. Offre un’ampia area per l’estrazione delle caratteristiche. L’impronta palmare è costituita da linee principali, rughe (linee secondarie) e creste epidermiche. Contiene altre caratteristiche come la texture, le tacche e i segni. Queste caratteristiche possono essere utilizzate per confrontare un’impronta palmare con un’altra. Il principale svantaggio della Trasformata di Stockwell (ST) è la quantità di informazioni ridondanti nella rappresentazione in tempo-frequenza che ne deriva. La DOST è stata proposta per migliorare l’efficienza computazionale della ST. La tecnica DOST accelera il calcolo ed elimina la ridondanza nel dominio spazio-frequenza.
