摘要

A method of extracting a region of interest from a tongue image and a health monitoring method and apparatus using the tongue image are provided. The health monitoring method includes constructing a database in which a tongue image obtained from a person, a template image set for the person, and a result of determining a health state of the person with respect to at least one characteristic factor are linked to one another; extracting a region of interest from a tongue image, which is acquired from a person whose health state is to be determined, using template matching; detecting at least one characteristic factor from the extracted region of interest; and determining the person's health state based on a change in a tongue state, which is detected from a comparison between the detected characteristic factor and a characteristic factor searched from the database with respect to the region of interest in different health states.
