颜色是舌诊所需的重要参考特征,实现消除食品偏色干扰、科学收集舌色数据,从而减少舌色误差避免造成误诊。首先进行舌像分割得到完整舌头,其次进行苔质分离,分别提取舌苔和舌质的颜色数据进行分析,然后提取出舌苔的主题色(K-means),最后依据主题色的区域分布进行伪彩色图像处理。通过对食品偏色与去干扰方法的探讨,得出了舌质颜色不易被食品改变,食品偏色易改变苔色,并构建一种舌色数据校正的方法。通过舌像采集以及预处理,对比研究了舌色的舌边色泽和舌中色苔的相对性关系,解决了食品偏色去干扰问题,为诊断应用收集数据,前景广阔,意义深远。Color is an important reference feature required for tongue diagnosis.It can eliminate food color deviation interfer⁃ence and scientifically collect tongue color data,thus reducing tongue color error and avoiding misdiagnosis.Firstly the tongue image is divided to obtain the complete tongue,secondly the tongue is separated,and the color data of the tongue coating and the tongue are extracted for analysis.Then the subject color of the tongue coating(K-means)is extracted.Finally,pseudo color image processing is performed according to the regional distribution of the subject color.Through the discussion of the method of food color deviation and de-interference,it is concluded that the color of the tongue is not easily changed by the food,the color cast of the food is easy to change the color of the moss,and a method for correcting the tongue color data is constructed.Through tongue image is collecting and preprocessing,a comparative study of the relative color of the edge of the tongue and central tongue of tongue coating.The prob⁃lem of food color deviation and interference is solved,and the data is collected for diagnostic application.The prospect is broad and profound.
