Anatomy of the Ear

Anatomy of the Ear

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

Purpose of the Study:

To introduce a novel 3D ear acquisition system for biometric applications.
To evaluate the efficiency and applicability of the proposed system for ear recognition.

Main Methods:

A new 3D ear acquisition system was developed utilizing the triangulation imaging principle.
The system focuses on capturing detailed 3D ear geometry for biometric analysis.

Main Results:

Experimental results demonstrate the efficiency of the developed 3D ear acquisition system.
The system's capability for effective ear recognition was validated.

Conclusions:

The proposed 3D ear acquisition system is an efficient and viable method for biometric identification.
Ear biometrics, facilitated by this novel system, presents a promising alternative to existing biometric modalities.
