Research on the Tongue Image Characteristics with Yin Deficiency Human Cleft Tongue
摘要
Abstract
Objective This paper introduces computer image digital processing technology combined with expert evaluation method to summarize the characteristics of human cleft tongue in Yin deficiency.Methods A total of 500 cases of tongue images from college students at Liaoning university of traditional Chinese medicine were included,with 60 cases featuring a bifurcated human tongue.Measured by nine body mass scales,35 cases of Yin deficiency were found,by random sampling method,100 cases were randomly selected from the smooth tongue image as control group,the OpenCV algorithm was used to extract the chromaticity space data of tongue quality,tongue coating HSI,and Lab;The Yolov 5 algorithm was used to analyze the characteristic parameters of tongue imagery,such as the ratio of crack width to tongue width,the ratio of crack height to tongue height,and the ratio of crack area to tongue area.By comparing the differences between the two groups of tongue images,the characteristics of cleft tongue images in Yin deficiency people were explored.35 cases of Yin deficiency and cleft tongue were divided into three-point groups to determine the correlation between Yin deficiency and the severity of Yin deficiency.Results Qualitative analysis:Compared with the control group,the human cleft tongue group was more likely to have red tongue,prickly tongue and thin tongue,and the tongue coating was prone to less lichen and thin lichen,and the tongue texture was dry and the sublingual veins were thicker(P<0.05).Quantitative analysis:Tongue characteristics:Compared with the control group,the H value of tongue in areas 1 and 4 of the human cleft tongue group were smaller(P<0.05).The S value of areas 2 and 4 were higher(P<0.05).The I value in areas 2,3 and 4 were high(P<0.05).The L value of areas 1,3,4 and 5 were high(P<0.05).Characteristics of tongue coating:H value in areas 1～4 were small;The S value in areas 2～5 were large(P<0.05).The I value in area 2 and area 5 were higher(P<0.05).The L value of area 2 was large(P<0.01).Quantitative characteristics of cracks:the ratio of crack area to total tongue area,crack width to tongue width,and crack height to tongue height in the human cracked tongue group were significantly higher than those in the control group(P<0.01).The results of quantitative numerical univariate analysis of human cracks showed that the numerical size of cracks under the score of Yin deficiency was positively correlated with the severity of Yin deficiency in the severe Yin-deficiency group>the moderate Yin-deficiency group>mild Yin-deficiency group(P<0.05).Conclusion This study analyzes the characteristics of human cleft tongue characteristics,which is closely related to Yin deficiency,and finds that the numerical size of human cleft tongue crack is positively correlated with the severity of Yin deficiency constitution,in order to provide an objective basis for the clinical application of human cleft tongue characteristics.关键词
