Towards Understanding the Symmetry of Human Ears: A Biometric Perspective

Free registration required

Executive Summary

In this paper, an analysis of the symmetry of human ears is presented. Such an analysis is essential in order to understand the possibility of matching the left and right ears of an individual, or to reconstruct portions of the ear that may be occluded in a surveillance video. Ear symmetry is assessed geometrically using symmetry operators and Iannarelli's measurements, where the contribution of individual ear regions to the overall symmetry of the ear is studied. Next, to assess the ear symmetry (or asymmetry) from a biometric recognition system perspective, several experiments were conducted on the WVU Ear Database.
