Current Status and Recommendations for the Development of International Standards for Computerized Tongue Image Analysis System

This study investigates the current status of international standards for Computerized Tongue Image Analysis Systems (CTISs) in the field of Korean medicine. Currently, international standards for CTISs primarily define general requirements, while standardized performance evaluation methods, a unified format for tongue image data, and reference standards for tongue diagnosis based on acquired images have yet to be established. This study analyzes the progress and limitations of CTIS standardization and proposes future directions to support the development and practical implementation of standardized CTISs in Korean medicine.
