利用分形模型对菌落的显微图象进行纹理分析，表面的覆盖维数是描述菌落的有效特征，并综合其灰度特性，抽取菌落的中央隆起部分，用于菌落的识别．结果说明分形模型用于诸如菌落具有自相似的物体的纹理分割是成功的．
The fractal model was used to analyze the microscopic image of the colony. The coverage dimension of the surface was an effective feature to describe the colony. Based on its gray characteristic, the central bulge of the colony was extracted for colony identification. The result shows that fractal model is successful for texture segmentation such as colony with self-similar objects.
