中文摘要：

将图像中的线条关系归纳为伴随、接连和包围三种,现有文献对接连关系有很多讨论和应用,但是对伴随和包围关系却缺少研究。对图像线条的伴随和包围关系进行讨论,给出刻画和计算方法,并通过人工数据实验和实际图像数据实验,验证了算法的有效性。

英文摘要：

This paper summarized the relationship between image lines into three categories： concomitance, succession, and surrounding. The succession relation was extensively researched and applied by the existing theories, but seldom discussed the concomitance and surrounding relations. This paper introduced methods and algorithms to describe and compute the concomitance and surrounding relations. It verifies the effectiveness of the algorithms by experiments on synthetic data and real image data.
