OpenCV-dlib-python3实现人脸戴墨镜和含Y的抖音效果

OpenCV

1 说明：
=====
1.1 吸烟有害健康！！纯属娱乐和学习Python的相关知识 。
1.2 虽然是娱乐，但是opencv、dlib和python在人工智能、人脸识别、自动化等有很大作用，目前已经或者未来会有更多的应用，作为一名普通人，学习一点知识很有必要 。
1.3 我的文章通俗易懂，小白都会，而且亲测过，没有编程经验的，一看就会！可以培养自己和孩子的学习计算机和编程兴趣！

2 准备工作：
========
2.1 环境：
华为笔记本电脑、深度deepin-linux操作系统、python3.8和微软vscode编辑器 。
2.2 要求：
2.2.1 PIL、numpy、imutils模块安装，安装简单，省略 。
2.2.2 cv2模块安装：
pip install opencv-python#下面是我的cv2模块相关初步介绍的文章https://www.toutiao.com/i6833713845005976067/2.2.3 dlib模块安装：有坑！！！
我是这么安装的，从github下载包，解压 。
https://github.com/davisking/dlib我是在桌面上，终端打开，输入：
python setup.py install#推荐#下面是我的安装#xgj@xgj-PC:~/Desktop/dlib/dlib-master$ sudo python3.8 setup.py install#本机安装

3 代码来源：
========
3.1 源代码：
https://github.com/tomoncle/face-detection-induction-course下载，解压，找到：
input_video_stream_paste_mask.py，进行修改 。
3.2 
shape_predictor_68_face_landmarks.dat下载
官网，网速慢，还有坑，建议下面地址下载 。
