The present invention discloses an identification method based on a
mathematical model for dividing the
tongue surface contour ring region for tongue diagnosis. S1. Tongue
image acquisition: During the process of obtaining the tongue image, the user logs in to the corresponding tongue diagnosis identification
software, and takes a picture of their own tongue through the image taking function in the
software. The present invention relates to the technical field of
tongue surface recognition. This identification method based on the
mathematical model for dividing the
tongue surface contour ring region for tongue diagnosis enables clearer subsequent
feature extraction and recognition through automated
processing of the image during the acquisition operation. At the same time, after dividing the position of the tongue image and determining and classifying the corresponding regions, through this digital partitioning calculation method, the tongue is divided into several corresponding regions, thereby obtaining the tongue color, petechiae, cracks, texture, fatness and thinness, etc. values of the corresponding regions, and analyzing the health status of the corresponding body parts, making computerized tongue diagnosis a reality.
