中文说明：根据霍夫变换进行直线检测，识别直线车道线。该代码不是matlab2012自带 hough函数编写，是直接编写hough变换算法进行实现的比较有学习价值。里面包含很多matlab hough变换检测车道线文献
English Description：
According to the Hof transform for line detection, identification of linear Lane line. The code is not matlab2012 comes with Hough function to prepare, is directly prepared Hough transform algorithm to achieve the comparison of learning value. Which contains a lot of Hough matlab transform detection lane line literature
