中文说明：针对传统的 Hough 变换和链码法存在的计算效率低和漏检、误检等问题，提出新的直线特征提取算法． 该算法在 Canny 边缘的基础上，使用一个聚类算法将边缘分类，缩小了检测直线的范围; 进一步剔除聚类结果中的伪直线; 最后使用改进的 Hough 变换，较快地将直线提取出来
English Description：
For classical Hough transform and calculation of the chain code method is inefficient and false, false detection problems, propose new line Feature extraction algorithms. On the basis of the algorithm the Canny edge, using a clustering algorithm to sort the edge, narrowed the range of line detection; Into the Step remove clustering results in a pseudo line; Finally, using modified Hough transform, fast extracting straight lines
