Biometric approaches of 2D-3D ear and face: A Survey

Abstract

The use of biometrics in human recognition is rapidly gaining in popularity. Considering the limitations of biometric systems with a single biometric trait, a current research trend is to combine multiple traits to improve performance. Among the biometric traits, the face is considered to be the most non-intrusive and the ear is the most promising candidate to be combined with the face. In this survey, existing approaches involving these two biometric traits are summarized and their scopes and limitations are discussed. Some challenges to be addressed are discussed and few research directions are outlined. © Springer Science+Business Media B.V. 2008.
