摘要
分析岩石节理图片,细化是关键的一步,它是分析节理拓扑结构的基础。由于二值节理图片噪声大,节理内部有空洞等特点,直接用现有细化算法得到的结果中存在大量毛刺和并非真实骨架的环形结构。本文针对这些问题提出了一种算法,把彩色图像中的信息加到了二值图像处理过程中。本算法细化后的结果更好地反映了岩石节理的骨架。
Image thinning plays a key role in analyzing of rock fracture images. Because of the noise in the rock images, there exist a lot of short lines and circles in the output of the common thinning algorithm, which form fake topological structure of the fractures. Various factors affect the thinning of the rock images, and result in false result. The effects of those factors on the thinning results are discussed in this paper. And a novel method is proposed for thinning of the rock fracture images. Simulation shows the effectiveness of the approach.
