Ear is a new class of relatively stable biometric that is invariant from childhood to early old age. In most cases techniques already working in other biometric fields, such as PCA are applied to ear. Eigen-ears provide high recognition rate only in closely controlled conditions. Indeed, even a slight amount of rotation can cause a significant drop in system performance and in unattended systems rotations...
Ear structure as a new class of biometrics can be used in many applications such as security systems. Ear structure is physiologically unique and stable, so ear recognition can be a good choice for a biometric security system. Even though, using ear biometric is not customary but it can be used with other biometrics like face or fingerprint simultaneously to increase the reliability of a biometric...
