A novel geometric feature extraction method for ear recognition

作者：

Highlights：

• We proposed a novel geometric feature extraction approach for ear image.

• Both the maximum and the minimum ear height lines are used to characterize the contour of outer helix.

• Our method achieves recognition rate of 98.33 on the USTB subset1 and of 99.6 on the IIT Delhi database.

• Our geometric method can be combined with the appearance approaches to improve the recognition performance.
