基于分形参数的中药材显微图象纹理分析

Texture Analysis of Chinese Traditional Medicinal Materials Micro graph Based on the Fractal Parameter

提出了一种基于分形维数分析中药材显微图象的方法。将中药材显微图象视为灰度纹理图象,依据分形布朗运动性质和功率谱法对4种中药材显微图象进行分维数计算。结果表明:中药材显微图象具有分形的特征,分维数能有效地描述纹理的结构与灰度,不同的显微图象对应不同的分维数,分维数可作为分析图象及进一步识别图象的一个定量参数。

In this paper,an approach based on the fractal parameter is developed for analyzing the Chinese Traditional Medicinal Materials micrograph.The Chinese Traditional Medicinal Materials micrograph is treated as texture image.According to Fractal Brown Motion and Power Spectrum method,fractal dimention is computed.The result shows that the Chinese Traditional Medicinal Materials micrograph possess fractal feature.Different micrograph is corresponding to different fractal dimension.The fractal dimension is a quantitative parameter which is applied to analyze and identify image.
