摘要
抽取直线方法是计算机视觉中尚待完善的问题之一 .在若干多尺度边缘检测方法的基础上 ,提出了把线结构作为一种尺度空间特征的新思路 .这样直线抽取过程就转化为尺度空间中的特征分析过程 .通过分析线结构在尺度空间中的演化规律 ,提出了一种稳健的直线抽取算法 .对合成图象和自然景物图象的实验结果表明了新方法的有效性 .
This paper discusses the method of straight line extraction, which is one of the open problems in computer vision. Based on the analysis of several multi scale approaches for edge detection, a new idea which straight lines are considered as a kind of feature structures in scale space is developed. Then straight line extracting is converted into the procedure of analyzing the features in scale space. After the characteristics of the line structures in scale space are analyzed, a robust approach for straight line extraction is presented. Experimental results on a synthetic image and several natural scene images indict new algorithm's effectiveness.
