PURPOSE
To evaluate the accuracy of detecting cephalometric landmarks automatically by computer.
MATERIALS AND METHODS
Digital image processing algorithms (edge-based and morphological) in addition to mathematical algorithms (knowledge-based) were used to develop a program for the identification of 15 lateral cephalometric landmarks on digital cephalograms.
RESULTS
The automatic landmark identification system was clinically acceptable (p > 0.05 comparing with 2-mm error range) for five landmarks.
CONCLUSION
The automatic landmark identification is accurate for only some landmarks. Additional studies may be necessary to improve this method.
目的
评估计算机自动检测头影测量标志点的准确性。
材料与方法
除数学算法（基于知识的）外，还使用了数字图像处理算法（基于边缘的和形态学的）来开发一个用于识别数字化头影测量片上15个侧位头影测量标志点的程序。
结果
自动标志点识别系统对于五个标志点在临床上是可接受的（与2毫米误差范围相比，p>0.05）。
结论
自动标志点识别仅对某些标志点准确。可能需要进一步研究以改进此方法。
