Self-health monitoring method based on comparative analysis of tongue color changes in TCM
Objective According to the principle that tongue color changes in Chinese medicine indicate human diseases,to propose a self-health monitoring method based on the comparative analysis of tongue color changes,so as to prevent the damage of unknown diseases to personal health and reduce the cost of personal health monitoring.Methods Personal tongue images were collected by image acquisition equipment.Using deep learning and traditional image processing technology,as well as leveraging the conversion relationship between RGB and CIE Lab color models,the characteristic value of tongue color was obtained to establish a self-health standard tongue image database.The new tongue image was collected,and the best matching template was identified from the database through the principle of anisotropic scaling template matching.Then the characteristic values of the tongue color changes of the newly collected tongue image and the best matching template tongue image were obtained through the difference comparison analysis method,and the self-health monitoring was carried out combined with the setting range of quantitative parameters.The effectiveness of the proposed method was finally verified by self-tongue anomaly simulation experiments.Results The setting of self-tongue color change thresholds was achieved through techniques such as self-tongue image database construction,anisotropic scaling template matching,and tongue color difference analysis.The tongue color of newly acquired tongue images can be extracted,the difference with the tongue colors in the standard tongue image database can be calculated,and the difference values can be compared with the set threshold value to monitor health.The validity and practicability of the proposed method was verified by the anomaly simulation experiments.Conclusion The self-health monitoring method based on the comparative analysis of tongue color changes in TCM can conveniently monitor personal health status,and play a certain role in promoting the objectification development of TCM tongue diagnosis.
