准备工作：

备份与恢复本地数据库 (localhost)：

在想要备份的应用目录下，meteor run。
还是在相应的应用目录下，meteor mongo，查看相应的端口号，比如：如果显示的是 connecting to: 127.0.0.1:3001/meteor，那么端口号就是3001，下一步要用到。

ffmpeg -f avfoundation -framerate 30 -s "640x480" -i "0" -c:v rawvideo -pix_fmt rgb24 -f caca -s "640x480" output4.mp4

brew install homebrew-ffmpeg/ffmpeg/ffmpeg --with-libcaca

ffmpeg -i vitrine.mp4 -vf scale=1024:-1 -q:vscale 0 vitrine.avi

This face-boxer.py script is more-or-less the same code that you'll find in the OpenCV tutorial: Face Detection using Haar Cascades. For another variation, with more explanation, check out RealPython's tutorial.

Usage

The face-boxer.py script is designed to be run from the command-line. It has two required arugments:

The path to a XML file containing a Haar-cascade of visual features. In this example, it will be the features that make up a face.
The path to an image file that you want to perform face-detection on. You can pass in more than one image file as space-separated arguments.
