摘要
研究计算机舌象分析方法,对进一步推动中医现代化,有重要作用。本文提出了一种同时包含位置和颜色信息的舌象特征表示方法,实现了中医观点下舌色的自动分类。提出把HSV颜色空间中极坐标系下的H、S分量转化为直角坐标系的X、Y分量,并以此作为颜色特征,比较了这两种颜色特征表达方法对分类结果的影响。实验结果表明,(X,Y,V)颜色特征表示方法具有更好的分类效果。
Automatic tongue color analysis is important for the modernization of traditional Chinese medicine. A new feature representation, which can depict the color and position information of tongue simultaneously, is proposed to simulate the tongue diagnostic process of Chinese medicine. Histograms on A XY color space transformed from HSV color space in polar coordinates is adopted to represent the color features of tongue. The effects of the two methods on tongue color classification are compared experimentally. Experiment results show that the new feature representation is efficient for simulating the traditional tongue diagnostic of Chinese medicine, and the transformed XY color space is better than HSV color space for the color classification of tongue color.
