Anatomical landmarks are considered the most objective indicators for use in forensic facial comparisons. Therefore, accurately identifying and locating these landmarks is the beginning of reliable facial comparison. This study evaluated the accuracy with which facial landmarks are located and examined their reliability according to type of landmark, head posture, and image quality. Nine operators located a series of landmarks on prepared facial images used to produce comparison images. Then, the average distances between the reciprocal landmarks (ADRL) on the reference and the comparison images were measured as indicators of landmark reliability. We found that a set of landmarks had higher or lower reliability as a function of the head angle and image quality. More reliable landmarks were associated with certain head postures and degrees of image quality. These should be used for facial comparison analysis depending on various head and image conditions.
解剖学标志被认为是用于法医面部比对的最客观指标。因此，准确识别和定位这些标志是可靠面部比对的开端。本研究评估了面部标志定位的准确性，并根据标志类型、头部姿势和图像质量检验了其可靠性。九名操作人员在用于生成比对图像的已准备好的面部图像上定位了一系列标志。然后，测量参考图像和比对图像上相互对应的标志之间的平均距离（ADRL），作为标志可靠性的指标。我们发现，一组标志的可靠性会因头部角度和图像质量而更高或更低。更可靠的标志与特定的头部姿势和图像质量程度相关。应根据各种头部和图像条件，将这些标志用于面部比对分析。
