本文提出了三维耳图像的一个独特特征：人的耳偏面角。耳廓面角特征定义为耳廓面法向量与耳廓面法向量之间的夹角。它是三维耳朵中独特而稳定的特征，能够提供索引识别和分层验证解决方案，提高了三维耳朵识别的速度和准确性。实验结果表明，在识别中使用角度分度，搜索范围比原搜索范围减少到9.69%，大大节省了时间。通过结合角度特征和迭代最近点（ICP）方法，验证实验也实现了等错误率（ERR）的提高（从2.8%降至2.3%）。(C) 2014 Elsevier B.V.版权所有
This paper proposes a unique characteristic in 3D ear images: ear-parotic face angle of the person. The ear-parotic face angle feature is defined as the angle between the normal vector of the ear-plane and the normal vector of the parotic face-plane. It is a unique and stable feature in 3D ears, and is able to provide indexing identification as well as hierarchical verification solutions which enhance both the speed and accuracy of 3D ear recognition. The experimental results show that by using the angle indexing in identification, the search range is reduced to 9.69% from the original, which is a considerable reduction in time. The verification experiment also achieved an equal error rate (ERR) improvement (from 2.8% to 2.3%) by combing the angle feature with iterative closest point (ICP) method. (C) 2014 Elsevier B.V.
