红酒论坛网站建设,潍坊关键词优化软件,网站上图怎么用ps做,男生女生做羞羞事的网站主要在官网给的Demo基础之上用OpenCV把特征点描绘出来了。很早之前写过一篇配置Dlib环境的博客，现在来稍微梳理下提取特征点的使用方法。上一篇配置环境博客地址：http://blog.csdn.net/zmdsjtu/article/details/52422847 惯例先放效果图吧&#xff1…

主要在官网给的Demo基础之上用OpenCV把特征点描绘出来了。

很早之前写过一篇配置Dlib环境的博客，现在来稍微梳理下提取特征点的使用方法。

惯例先放效果图吧：

动图如下：

接着就是简单粗暴的代码：
