这篇文章主要为大家详细介绍了face++与python实现人脸识别签到(考勤)功能，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

项目实现利用face++开发一个课堂签到的软件，实现面向摄像头即可完成记录学号、姓名和时间的签到工作。

非常感谢你的阅读

大学的时候选择了自学python，工作了发现吃了计算机基础不好的亏，学历不行这是

没办法的事，只能后天弥补，于是在编码之外开启了自己的逆袭之路，不断的学习python核心知识，深入的研习计算机基础知识，整理好了，如果你也不甘平庸，那就与我一起在编码之外，不断成长吧！

其实这里不仅有技术，更有那些技术之外的东西，比如，如何做一个精致的程序员，而不是“屌丝”，程序员本身就是高贵的一种存在啊，难道不是吗？ [点击加入] 想做你自己想成为高尚人，加油！
