基于图象处理的舌苔润燥分析方法的研究

An Image Processing Based Method to Analyse Moisture of Tongue Fur

二分光反射模型描述了物体的光反射机理，它认为物体表面的颜色由面反射和体反射组成。为了采用图象处理技术进行舌苔润燥分析，提出一种基于二分光反射模型的有效方法；研究了亮斑的成因及ＣＣＤ摄像机特性对彩色图象成像的影响，较好地解决了亮斑的检测和识别问题；并进一步对这种舌苔润燥分析方法的应用结果进行了探讨。

The Dichromatic Reflection Model describes the color of the reflected light as a mixture of light from surface reflection and body reflection. In this paper, an effective method using image processing for analyzing moisture of tongue fur based on the Dichromatic Reflection Model is introduced. The formation of the highlight areas and the influence of the characters of CCD camera to the formatted color image are studied here. The presented method gives a good result to the highlight areas detection and recognition. And the application of this method to analyse moisture of tongue fur is discussed.
