Python Face Recognition Web Service

While working on Camera Live Stream Service, I decided to add machine learning to this project. That means our camera can learn who the family members are, and during the video stream, send warning to the owner if someone on camera is not a family member. That is just one idea; you may have more ideas about how to use this with other devices - maybe even a door opener.

IDE for Python Development Pycharm

Download Pycharm development tool: https://www.jetbrains.com/pycharm/download/

Python Virtual environment Installation

sudo pip install virtualenv

Create new python project

mkdir project
cd project
virtualenv venv

Setup Boost Python

We need boost python when compile Dlib c++ for Python module.

To compile Boost.Python yourself download boost from http://boost.org and then go into the boost root folder.

./bootstrap.sh --with-libraries=python
./b2
sudo ./b2 install

Setup dlib C++ library

Dlib is a modern C++ toolkit containing machine learning algorithms and tools for creating complex software in C++ to solve real world problems. https://github.com/davisking/dlib

brew install cmake
git clone https://github.com/davisking/dlib.git
cd dlib
mkdir build; cd build; cmake .. -DDLIB_USE_CUDA=0 -DUSE_AVX_INSTRUCTIONS=1; cmake --build .

Activate Python Virtual Environment in our Python project

cd /PATH-OUR-PROJECT
cd venv
source bin/activate
python setup.py install --yes USE_AVX_INSTRUCTIONS --no DLIB_USE_CUDA

Flask

Use flask as Python framework to build API service. API: http://flask.pocoo.org/docs/0.12/api

from flask import Flask,Response,json
app = Flask(__name__)
@app route('/', methods=['GET'])
def home():
  return Response(json.dumps({"api": "1.0"}), status=200, mimetype='application/json')
if __name__ == "__main__":
  app.run()

Database

We can use any database to store users info. In this project I just use sqlite3 default support by Python. Tool for design slqlite: http://sqlitebrowser.org/
