Computer-assisted image analyses were performed on the color of the tongues of 95 medical students to enhance the accuracy and objectivity of tongue inspections for determining blood stasis. Areas from the sublingual vein were selected and subjected to image analysis. A slide scanner was used to digitize the color slides, and the digital information was transmitted to a personal computer for subsequent feature extraction and analysis. A comparison was then made between the computerized data using Red-Green-Blue color components, and inspection with the naked eye based on the diagnostics of traditional Chinese medicine. The results obtained suggest that there are statistically significant correlations between visual analyses and the computerized normalized R value (F value; 3.397, p < 0.05). The examination of sublingual veins with the naked eye showed the validity of computer-assisted image analysis. This analysis may provide a potential solution to the demand for a sophisticated means of quantitative and qualitative observation of physiological parameters regarding blood stasis, including that for the sublingual vein.
对95名医学生的舌色进行了计算机辅助图像分析，以提高判断血瘀的舌诊准确性和客观性。选取舌下静脉区域进行图像分析。使用幻灯片扫描仪将彩色幻灯片数字化，并将数字信息传输到个人计算机进行后续特征提取和分析。然后将使用红-绿-蓝颜色分量的计算机数据与基于中医诊断的肉眼检查进行比较。所得结果表明，视觉分析与计算机化的标准化R值之间存在统计学上的显著相关性（F值；3.397，p<0.05）。肉眼检查舌下静脉显示了计算机辅助图像分析的有效性。这种分析可能为对包括舌下静脉在内的血瘀生理参数进行复杂的定量和定性观察手段的需求提供潜在解决方案。
