摘要
[目的]运用色度学的方法对各类舌色的量化特征进行了研究,以期为舌色判断的客观化提供依据。[方法]对207幅各类舌色图谱扫描后,分析取样点R(红)、G(绿)、B(蓝)各分量值与其总和的比值。同时对青紫类舌色的以上述指标进行聚类后,再与其他常见舌色进行组间比较。[结果]淡白舌G比最高,R比和B比居中;红色类舌R比最高,G比和B比较低;青紫类舌B比最高,G比居中,R比最低。淡白舌NR+NG+NB最大,红色类舌最小,青紫类舌居中。[结论]不同中医专著中的舌色图谱呈现一定的色度学规律,但其参数的使用宜结合临床实际。
[ Objective]Quantitative characteristics of tongue color is investigated by colorimetrical method to supply evidence for the objectivity of tongue inspection. [Methods] Two hundred and seven tongue pictures with different tongue color were scanned. The values of R (red) , G (green) and B (blue) of different sampling spots in the pictures, as well as their ratios with the total value of R + G + B were observed. Purple-bluish tongue was clustered with the above indexes and then was compared with other common-colored tongue color. [Results] In light white tongue, G ratio was high, R ratio and B ratio low; in red tongue, R ratio was high, G ratio and B ratio low; in purple-bluish tongue, B ratio was higher, G ratio high and R ratio low. The total value of R + G + B was higher in light white tongue, high in purple-bluish tongue and low in red tongue. [Conclusion] There are colorimetrical characteristics in tongue pictures from different monographs of traditional Chinese medicine, but the colorimetric parameters of the tongue pictures should be applied according to clinical cases.
