The outer ear is an emerging biometric that has drawn the attention of the research community for more than a decade. Empirical studies confirm, that the shape of the outer ear is unique, and it is also assumed to be stable throughout a human life time. This work represents the first study on ear recognition where evaluations on public 2D/3D ear datasets are performed along with experiments on realistic data. Our dataset comprises of 3D images, mugshots and CCTV footage.

This work introduces several approaches for processing ear images and also evaluated state-of-the art descriptors w.r.t. their suitability to ear recognition, their robustness to signal degradation and clustering tendencies.
