Research of Identifying Traditional Chinese Medicine Constitution Model Based on Human Skeleton Feature
Objective Traditional Chinese medicine(TCM)constitution identification mainly relies on filling out constitution questionnaires,which has a certain degree of subjectivity.Subsequently,the methods based on tongue and facial features for iden-tifying constitutions have emerged,laying the foundation for objective constitution identification.However,these methods often re-ly on specialized equipment such as tongue and facial diagnosis instruments.This study aims to propose a TCM constitution iden-tification model based on human skeletal features that only rely on an indoor optical camera and to explore the feasibility of exten-ding the input features of constitution identification to the whole body.Methods This study collected the height,weight,gender and full-body posture images of the participants and asked them to fill out constitution questionnaires.The questionnaire results were used as data labels.Deep learning algorithms were employed to extract human skeletal features and neural networks to es-tablish the relationship between height,weight,gender,skeletal features and the constitutions of.Then,it established a TCM con-stitution identification model based on skeletal features and evaluated its performance based on the constitution questionnaires filled out by the participants.Results The experimental results showed that the TCM constitution identification model based on human skeletal features achieved a certain degree of accuracy on the sample data and can achieve accuracy similar to that of the tongue-based constitution identification model with only an indoor optical camera.Conclusion The TCM constitution identifica-tion model based on human skeletal features can achieve constitution identification with only an indoor optical camera and is more objective than traditional constitution questionnaires and more convenient than methods based on tongue and facial features.In the future,multimodal fusion of such methods can complement each other's strengths and further improve the objectivity,intelli-gence and multimodality of TCM constitution identification.
