Two kinds of algorithm have been set forth to estimate the symmetry characteristic of live human skull on CT image. These CT images were treated with a series of processes such as coding into programs, formatting originals, binary coding, rectifying image deviation, detecting boundary edge, and quantitatively measuring the skull symmetry. The statistical analyses of measuring 3000 live human skull images have worked out the ratio and the distribution of the skull symmetry, so that dependable data are provided for establishing the human head injury biomechanics model. The results are of great practical value in the fields of anatomy, clinical medicine, biomechanies study, head injury analysis, etc.
已经提出了两种算法来估计CT图像上活体人类颅骨的对称性特征。这些CT图像经过了一系列处理，如编码成程序、格式化原始图像、二进制编码、校正图像偏差、检测边界边缘以及定量测量颅骨对称性。对3000张活体人类颅骨图像测量的统计分析得出了颅骨对称性的比例和分布情况，从而为建立人体头部损伤生物力学模型提供了可靠的数据。这些结果在解剖学、临床医学、生物力学研究、头部损伤分析等领域具有重要的实用价值。
