Definition

The term ear biometrics refers to automatic human identification on the basis of the ear physiological (anatomical) features. The identification is performed on the basis of the features which are usually calculated from captured 2D or 3D ear images (using pattern recognition and image processing techniques). The ear features that can be used in the process of identification are, for example, geometrical ear structure, characteristic ear points, global ear image features, local ear image features, and 3D models. The advantages of human ear as biometric as well as the overview of various approaches to ear biometrics are presented in the ear biometrics overview entry.

Introduction

As pointed out by Hurley et al., ear biometrics is no longer in its infancy and has shown encouraging progress [1]. It is due to the fact that the ear is the very interesting human anatomical part for passivephysiological biometric systems. It means that the subject does not have to take active...
