Although several papers have recently been devoted to establishing the validity of identification using the ear, this part of the human body still remains underexploited in forensic science. The perfect overlap of two images of the same ear is not really possible, but photographs of the ears as a reliable means of inferring the identity of an individual are poorly treated in the literature. In this study, we illustrate a simple, reproducible method, which divides the photograph of an ear into four parts-helix, antihelix, concha, and lobe-by means of a suitable grid of four straight lines. Although the division does not follow exact anatomical features, their edges do join anatomical points which are more easily identifiable. Measurement of certain areas of these parts can be combined to produce a code allowing personal identification. This method produces false-positive identifications of <0.2%. Last, the repeatability and reproducibility aspects of the method are tested.
尽管最近有几篇论文致力于确立耳部识别的有效性，但人体的这一部分在法医学中仍未得到充分利用。同一耳朵的两张图像很难完全重叠，然而，作为推断个体身份的可靠手段，耳部照片在文献中却未得到充分探讨。在本研究中，我们阐述了一种简单且可重复的方法，该方法借助由四条直线构成的合适网格，将耳部照片分为四个部分——耳轮、对耳轮、耳甲和耳垂。尽管这种划分并不完全遵循精确的解剖特征，但其边缘确实连接了更容易识别的解剖点。对这些部分的某些区域进行测量，并将测量结果组合起来生成一个代码，从而实现个人识别。该方法的误识率小于0.2%。最后，对该方法的重复性和再现性进行了测试。
