目的：探讨中药饮片完整性对横切面图像纹理特征参数的影响。方法：选取纹理特征各异的槟榔、大黄、白术3种中药饮片，采用矩形切和扇形切从完整饮片中等比例的截选部分作为样本，基于灰度共生矩阵和灰度梯度矩阵提取26个横切面图像纹理特征参数，比较部分饮片与完整饮片、矩形切与扇形切之间特征参数的异同。结果：对于具有放射状或环纹的槟榔和大黄，扇形切的部分饮片与完整饮片的纹理特征参数具有较好的一致性，矩形切的部分饮片与完整饮片的一致性较差；对于具有不规则纹理特征的白术，矩形切的部分饮片与完整饮片的纹理特征参数大致相同。结论：不完整的中药饮片能否代表完整饮片的纹理特征参数，既和饮片自身的纹理特点有关，又与不完整饮片的形状有关。本研究为图像采集时中药饮片的选取提供了依据，为获取准确的纹理特征参数提供了保障。

This study was aimed to explore the impact of integrality of Chinese herbal medicine on parameters of tex-ture feature in transverse section images. Three Chinese herbal medicine of Semen Arecae, Radix et Rhizoma Rhei and Radix A tractylodis Macrocephalae with different texture features were taken as research materials. Parts of Chi-nese herbal medicine were cut off from the whole by equal proportions. The 26 parameters were extracted by gray-level co-occurrence matrix and grayscale gradient matrix. The similarities and differences of 26 parameters of texture feature in the parts and whole, rectangular and fan-shaped Chinese herbal medicine were compared. The results showed that parameters of Semen A recae and Radix et Rhizoma Rhei with radial or annular texture had better con-sistency in whole and fan-shaped parts. Parameters of Radix A tractylodis Macrocephalae with irregular texture fea-ture were approximately the same in the whole and rectangular parts. It was concluded that whether parameters of texture features in parts Chinese herbal medicine can present the whole were related to its texture feature and the shape of the parts. This study provided the basis for collection of Chinese herbal medicine when sampling images. It also laid a foundation for the extraction of accurate parameter of texture feature.
