基于分形理论的中医数字化舌象苔质纹理分析

Analysis of traditional Chinese medicine digital tongue texture based on fractal theory

以分形理论为基础,设计实现计算数字化舌图分形维数的算法,并运用这一算法计算标准环境下采集的431例数字化舌图样本数据分形维数,通过对样本数据计算结果的统计分析,得出验证结论,分形维数对舌苔的厚薄、腐腻等数字化舌图图像特征敏感,可作为数字化舌象纹理分析的有效参考参数,在增加样本量的基础上可实现客观化分类标准的制定。

Based on the fractal theory,we designed a computing algorithm of digital tongue fractal dimension to calculate fractal dimensions of 431 cases of digital tongue samples collected in the standard environment.According to the statistical results,we concluded that fractal dimension was sensitive to digital tongue texture,such as thick fur,thin fur,curdy fur and greasy fur.Therefore,the fractal dimension could provide effective reference parameters for digital tongue texture analysis.Additionally,it would be expected to achieve the development of objective classification standard with an increasing sample scale.
