Embodiment Construction

[0033] The psychophysical visual experiments involved in the present invention are all carried out under darkroom conditions. A color-corrected LED display is used to display stimulus color blocks, and psychophysical experiments are performed on more than 24 observers with normal color vision. For the specific implementation process, please refer to the attached figure 1 ,as follows:

[0034] For the analysis and research of tongue color diagnosis, since the CIELab system is a color measurement system that describes visual perception, the description of color does not depend on the equipment used, so when analyzing tongue color, it can measure tongue color more objectively and truly. . Studying the color gamut distribution and classification of tongue color in this space is more in line with the actual situation of tongue color visual judgment in traditional Chinese medicine, and can more accurately find the relationship between the quantitative description of tongue color a...

Abstract

The invention relates to a traditional Chinese medicine tongue color classification perception quantification method combined by an equal sense distance method and cluster analysis, which belongs to the field of objective research of traditional Chinese medicine inspection. Tongue color classification boundaries are determined by using cluster analysis, tongue color type description rules in traditional Chinese medicine tongue inspection are used as psychological perception evaluation guiding basis, and an equal psychological perception distance scale is established for each classification by using the equal sense distance method. A mathematic relation model between tongue color physical quantities and psychological perception quantities is constructed, so as to obtain the psychological perception quantities which correspond to the tongue color physical quantities and conform to traditional Chinese medicine tongue color cognitive rules. The traditional Chinese medicine tongue color classification perception quantification method is characterized by aiming to establish an equal distance scale for tongue color classification by using a dichotomy, so as to increase the tongue color quantification accuracy of traditional Chinese medicine tongue inspection description habits and achieve the purposes of traditional Chinese medicine tongue color quantitative and qualitative description.

Description

technical field [0001] The invention belongs to the research field of objectification of traditional Chinese medicine inspection, and particularly relates to the field of tongue color quantification in traditional Chinese medicine inspection, which is used to improve the accuracy of tongue color quantification and grading that changes with diseases and conforms to the cognitive law of traditional Chinese medicine. Background technique [0002] Tongue diagnosis in TCM is a diagnostic method to understand the physiological functions and pathological changes of the human body by observing changes in tongue images, and plays an important role in clinical diagnosis of TCM. The traditional tongue diagnosis method relies on the visual observation and language description of TCM, and lacks quantitative description indicators and objective recording means, which brings difficulties to the description and classification of TCM tongue diagnosis. With the development of modern scientifi...
