| 摘 要： | 该文研究了一种在图像中提取直线的算法。直线提取需要尽量将那些因噪声影响而断裂的直线连接起来,同时,还要尽量避免过度连接,才能形成正确反映图像事件实质的特征。该文使用了多种特征作为判断直线是否可以连接的证据,因而降低了误判的可能。对仿真图像和真实图像所做的实验显示了该算法的有效性。

| Abstract: | An algorithm of extracting straight lines in images is researched in this paper.Line extraction should try to link those lines fragmented by noise,and avoid over-link in the mean time ,in order to get features that reflect correctly characters of image events.In this paper,multi-features are used as evidences of whether the lines can link or not,which reduces the possibility of wrong decision.Experiments on both synthetic and real images show the validity of this algorithm. |

| Keywords: | image understanding straight line extraction multi-feature fusion evidence theory |
