Abstract
Background and Purpose: Mizaj (Temperament) identification is an important stage of diagnosis in Persian Medicine (PM). This study aimed to evaluate thermal imaging as a reliable tool that can be used instead of subjective assessments.
Materials and Methods: This study was conducted in the winter of 2020 at the Behesht Traditional Medicine Health Clinic (Tehran, Iran). The Mizaj (Temperament) of 34 participants was assessed by a PM specialist using Mojahedi Mizaj standardized Questionnaire (MMQ). Also thermal images of the wrist at the radial pulse location, the back of the hand, and their whole face were recorded by a thermography camera model T2 (ULIRVISION Co.) and the temperatures of regions of interest were measured.
Results: Twelve thermal features were extracted and a classifying algorithm was designed based on a genetic algorithm and an Adaboost classifier. By selecting 7 of the 12 features that had the most impact on the classification, the mean accuracy of 85.6%, sensitivity of 66.7%, and specificity of 91.7% were obtained.
Conclusions: The thermal imaging was significantly consistent with MMQ and can be used as a reliable tool for evaluating dry/wet Mizaj (Temperament).
