Embodiment Construction
[0038] Principle of the present invention and process are further described below in conjunction with accompanying drawing:
[0039] 1. Color model training
[0040] 1.1. Fuzzy C-means clustering (FCM) for tongue color
[0041] The fuzzy C-means algorithm (FCM) is an improvement to the ordinary C-means algorithm. It uses the degree of membership to determine the degree to which each sample belongs to a certain category, and minimizes the FCM objective function through repeated iterations, so that the similarity between objects classified into the same category is the largest, while the similarity between different categories is the smallest.
[0042] 1.2. Tongue color calibration based on expert knowledge
[0043] In combination with Figures 1-5, the present invention selects 14 typical tongue samples of fur color, quality and color from the tongue image database of the Harbin Institute of Technology Research Center for Bioinformatics, and selects 20-50 samples for each colo...
