Recognizing and Identifying Individuals' Identity by Use of Biometrics of Ear

In comparison with other physical features, biometrics of ear has both advantages and limitations. Its small rank and its relatively simple structure bring about a controversial discussion. From a positive aspect, these features, in comparison to face recognition make it possible to have a faster processing and in comparison to fingerprinting provide an easier recognition method. From a negative aspect, the smallness of ear increases the possibility that it will be covered. In this paper, the authors have designed a biometric system by usage of a two-dimensional image of human ear in which moments are used to describe ear.
