高光谱成像系统在中医舌诊中的应用研究

舌诊是传统中医诊病的重要方法,然而传统舌诊中存在一个很大的问题是具有主观性,难于进行定量化描述.随着计算机技术的发展,图像处理和模式识别技术正在用于舌诊的辅助诊断.目前舌图像的采集方法基本都是使用数码相机,所提供的舌图像包含的病理信息有限,使得分析算法非常复杂且效果不甚理想.针对这种情况,提出使用高光谱成像系统代替数码相机进行舌图像的采集.由于高光谱舌图像具有丰富的图谱信息,初步试验表明了这一方法的有效性,为中医舌诊提供了一种新方法.

APPLICATION OF HYPERSPECTRAL IMAGING SYSTEM IN TONGUE ANALYSIS OF TRADITIONAL CHINESE MEDICINE

Tongue diagnosis is an important diagnostic method in traditional Chinese medicine(TCM).However,one important problem in tongue diagnosis is that its practice is subjective,qualitative and difficult in automated diagnosis.Recently it is a trend to utilize the image processing and pattern recognition technology in aid of the quantitative analysis of tongue image.As the tongue image is often acquired by a commercial digital camera,the pathological information that the image can provide is very limited.In this study,a hyperspectral imaging system,instead of a digital camera was used to acquire the image of the patient's tongue.Experimental results demonstrate that the hyperspectral tongue image acquired by the hyperspectral imaging system has more pathological information of the tongue.It is a new approach for tongue inspection of TCM.
