 # Face Detector
 A simple **Python** script implemented with **OpenCV**.\

 Try connecting your phone's camera to your PC for better quality and more detection accuracy of course. Just don't forget to change the index of `VideoCapture` (line **26**) to change the camera in use (try changing indexes until you find the suitable camera).
 
 ## How to run
-First you need to download and install [Python3](https://www.python.org). After that you have to run the file which named `faceDetector.py`.\
-After that download files from [releases section](https://github.com/mehrshaad/Face_Detector/releases) and extract them.\
-Then open `CMD`, `Terminal` or `shell` (whatever you call it! 🙂) in that folder, and enter:

-**NOTE**: use `python3` instead of `python`, if you're running on*Linux* or *MacOS*.\
-This command should start the script. After that it may take a while till a window appears, because at the first run it'll start to download and install opencv and numpy python packages (if you didn't have them already) which need to download about *60mb* of files, then you good to go!
