Abstract: Even though ear shape is used in forensic investigations, an ear identification system for assisting forensic experts is not well developed. One of the reasons for this is the three-dimensional (3D) concave shape of the ear; this changes its two-dimensional (2D) appearance when camera angles change. 3D statistical modelling is necessary to compensate for these changes in 2D appearance. In this study, we aim to increase the number of 3D statistical ear models based on a few forensic classification methods of ear shapes. Experimental evaluation shows that morphological classification based on the antihelix can improve the robustness of ear recognition against the change in camera angles.
