中医常见面诊图像颜色参数范围探讨

Exploration on the paramater range of common color of face diagnosis images in traditional Chinese medicine

目的:探讨自然人群面诊图像常见颜色特征的参数范围,为面诊图像常见颜色分类的判别标准提供依据。方法:系统整理本课题组积累的面诊图像资料,运用单因素方差分析统计20641名不同民族自然人群面诊图像常见颜色特征参数的变化,探讨其参数范围。结果:正常面色参数L值、a值、b值95%CI范围分别为138.64~138.94、143.47~143.56、145.95~146.04。面色L值比较,面色赤组、面色黑组L值显著低于面色正常组(P<0.05),面色青组、面色黄组、面色白组L值显著高于面色正常组(P<0.05),变化趋势为面色白组>面色青组>面色黄组>面色正常组>面色赤组>面色黑组;面色a值比较,面色青组、面色黄组、面色白组a值显著低于面色正常组(P<0.05),面色赤组、面色黑组a值显著高于面色正常组(P<0.05),变化趋势为面色赤组>面色黑组>面色正常组>面色黄组>面色青组>面色白组;面色b值比较,面色赤组、面色白组b值显著低于面色正常组(P<0.05),面色青组、面色黄组、面色黑组b值显著高于面色正常组(P<0.05),变化趋势为面色黄组>面色黑组>面色青组>面色正常组>面色赤组>面色白组。结论:本研究建立的自然人群面诊图像常见颜色特征的参数范围,可为面诊图像常见颜色分类的判别标准提供依据。

Objective: To explore the parameter range of common color characteristics of face diagnosis images of natural people, so as to provide the basis for the discrimination standard of common color classification of facial images, and the range of color parameters was discussed. Methods: Systematically sort out the data of face diagnosis images accumulated by the research group, One way ANOVA was used to analyze the changes of common color characteristic parameters of 20 641 face diagnosis images of natural people of different nationalities. Results: The 95%CI range of normal complexion parameters were:value L was 138.64-138.94, value a was 143.47-143.56, value b was 145.95-146.04. The comparison of value L complexion: the value L of red complexion group and black complexion group was significantly lower than that of the normal complexion group(P<0.05), and the value L of cyan complexion group, yellow complexion group and white complexion group was significantly higher than that of the complexion normal group(P<0.05), and the change trend was: white complexion group>cyan complexion group>yellow complexion group>normal complexion group>red complexion group>black complexion group;The comparison of value a complexion: the value a of cyan complexion group, yellow complexion group and white complexion group was significantly lower than that of the normal complexion group(P<0.05), and the value a of red complexion group and black complexion group was significantly higher than that of the normal complexion group(P<0.05), and the change trend was: red complexion group>black complexion group>normal complexion group>yellow complexion group>cyan complexion group>white complexion group;The comparison of value b complexion: the value b of red complexion group and white complexion group was lower than that of the normal complexion group significantly(P<0.05), the value b of cyan complexion group, yellow complexion group, black complexion group was higher than that of the normal complexion group significantly(P<0.05), the change trend was: yellow complexion group>black complexion group>cyan complexion group>normal complexion group>red complexion group>white complexion group. Conclusion: The parameter range of common color features of face diagnosis images of natural people established in this study, can provide the basis for the discrimination standard of common color classification of face images.
