| 摘 要： | 针对纸印品和表格中直线特征的提取，给出游程、块邻接图等定义，在上述定义的基础上，提出了一种基于游程块邻接图的纸印品直线特征提取的连通域分析算法。给出了基于此算法的两种纸印品图像直线特征检测结果，并对此算法的复杂性进行了分析，从测试结果与算法分析可以看出，此算法在提取纸印品直线特征时具有运算量小、准确、高效和抗干扰性强等特点，且易于编程实现。

| Abstract: | The definitions of run length and block adjacency graph (BAG) were given, according to paper's and form's straight line based on primitive extraction. The connected region analysis algorithm for straight line feature extraction was proposed based on run length BAG. Some experimental results of paper's straight line extraction were given. The computational complexity of algorithm was analyzed. The algorithm was precise, efficient and roustabouts, and easy to be realized by computer programming. |
