This the likelihood is temporary for a lot of websites rely on to collect, visit quantity is returned still considerable, but if you are collected everybody has collected the website, or you never had updated is to be achieved formerly, it is oneself are written, it is to mend one's ways of the character, your website is dangerous, searching engine know, the collects now order on Internet is increasing, more and more center institutes are lazy, thought to find support, collect all the day, but be not alled alone by search engine is collected namely, visit a quantity to go up not to go namely, likelihood you are this reason guide come, hope you calculate collect content, be about to change, search what engine can think you are to be achieved formerly so.

这个可能暂时来说很多网站都是靠采集的，访问量还依然可观，但是假如你采集的网站都是大家都已经采过的，或者你从来没有更新过一篇是原创、是自己写、是改过文字的，那你的网站危险了，搜索引擎是知道的，互联网上现在采集的程序越来越多，越来越多的站长学会偷懒，认为找到了依靠，整天采集，可是就是不被搜索引擎收录，就是访问量上不去，可能你就是这个原因导至的，希望你就算采到内容了，就要改一改，这样搜索引擎就会认为你是原创的了。

Firstly, preprocess road image with edge operator to get the edge information, then construct a deformable template model of road contour and its likelihood function which define the fitting degree for a given group of deformable template parameters, finally genetic algorithm is used to search the global optimal value of the likelihood function to get the optimal parameter of the deformable road model.

真实场景的道路识别算法常常受到光照变化的影响，导致图像序列中道路目标的亮度值变化较大，传统基于固定阈值的方法不能很好的解决该问题，因此道路识别算法鲁棒性差，即使道路检测和识别算法在光照较为固定的场景具有较好的效果，但这样的算法很难移植到其它光照场景。
