摘要
由于岩石表面粗糙,采用凹点分离方法很难正确地分离相互粘连的岩石图像。从细化的角度出发,研究和发展了一种粘连岩石分离的新算法。其主要思路是:首先细化提取岩石的骨架并计算骨架各点到岩石边界的距离,然后利用骨架边界距离函数波谷的特性将相互粘结的岩石分离。新算法提出了一种计算骨架边界距离值的新方法用于分析骨架波谷的特征,并在理论和实践的基础上,提出一种新的粘连岩石分离准则,有效地提高了岩石图像的分割效果。
For the stones edge is rough, it＇s difficult to separate the stones adhered to each other based on the concave points. This paper presents a new algorithm for stone image separation basing on stone thinning. The main procedures are： obtaining skeletons of stones regions based on the thinning and calculating the value of the distance to the stone edge, then using distance function to analyze the properties of skeletons and to split touched objects. In the algorithm, a new method of skeleton used for computing distance function properties is proposed, and splitting rulers for touched objects are developed based on theoretically analysis and practice experience.
