| 摘 要： | 线特征提取是计算机视觉中重要的低级处理过程，而多尺度分析是采用微分几何方法进行线特征提取时一个重要内容。研究了在对不同宽度线特征进行检测时，尺度因子的选择问题，分析了变化的线宽与特定尺度因子间的关系，得到新的尺度因子确定方法。实验表明该方法简单、省时、有效。

| Abstract: | Line feature extraction is one of the important low-level processes in computer vision. Multi-scale analysis is a crucial matter for line detection by differential geometry. The paper concerned the problem of how to choose proper scale factor for line extraction with different widths. The relationship between variable line width and a given scale was analysed, and a new scheme to determine scale was presented. Experiments show that the method is simple, time-saving and valid. |
