Embodiment Construction
[0034] The psychophysical experiments involved in this method are all carried out under dark room conditions. The stimulus color blocks are displayed on a color-corrected LED monitor, and the psychophysical experiments are performed on more than 10 observers with normal color vision. The specific implementation process is as follows:
[0035] 1. Determination of the psychological perception measurement range of facial complexion:
[0036] (1) To collect various standard image samples of complexion in traditional Chinese medicine, which need to include normal color, white, yellow, red, cyan, and black use cases, a total of 6 categories; each type of use case needs to contain more than 100 examples, and three The above TCM doctors give the type of calibration. Image acquisition requires accurate white balance and exposure settings to output image data in a certain color space, such as sRGB space, to ensure the standardization of image data.
[0037] (2) Extract the physical co...

The invention discloses a method for quantifying the complexion psychological perception and judging the adaptability, and belongs to the field of objectification study of color inspection in traditional Chinese medicine. The method comprises the steps of determining chromaticity physical stimulation quantities of two ends of a measurement range of psychological perception of all types of complexions on the basis of collecting all types complexion samples; meanwhile, determining an initial equidistant unit of each type of complexion psychological perception through a psychological and physical test; uniformly and equally dividing the measurement range for the psychological perception of each complexion according to the equidistant unit, and obtaining an initial perception equidistant color lump; regulating the physical stimulation quantity of each equal division point by an observer to reach uniform equal division in the psychological perception, and obtaining a final psychological perception equidistant color lump; computing a perception quantifying result of the final psychological perception equidistant lump on each complexion through regression modeling; finally, judging a type to which the complexion belongs by taking the neck color as the contract color. According to the method disclosed by the invention, the one-dimensional perception quantification on each complexion can be realized, and the one-dimension quantity value on perception coordinates of each complexion can be obtained; meanwhile, the neck color in normal color of an individual can be expressed in a combining way, and the adaptability analysis on the type of each complexion can be realized.
Description
technical field [0001] The present invention belongs to the field of research on the objectification of color diagnosis in traditional Chinese medicine, and in particular relates to the field of complexion quantification in color diagnosis in traditional Chinese medicine. judge. Background technique [0002] In the color diagnosis of traditional Chinese medicine, the doctor visually observes under natural light and conducts judgment and analysis. This method is highly subjective and is easily affected by time, seasons, climate and other conditions, resulting in the discrimination of facial color varies from person to time and place, and it is difficult to obtain objective and quantitative information, which is useful for clinical, teaching and scientific research. It has brought a lot of inconvenience and hindered academic exchanges. With the development of modern scientific and technological means in TCM diagnosis, the research on the objectification and standardization o...
