An image processing web server using Node.js and Python

This project was developed using:

• Node.js v8.11.3
• npm 6.1.0
• Python 2.7
• Jade
• Bootstrap v4.1.1
• jQuery v3.3.1

The following packages are required by the Node.js application:

• express
• express-fileupload
• stylus
• morgan
• nib
• request
• fs
• image-size

The Python application requires Keras v1.1.2 with backend Theano v0.9, and Flask 1.0.2.

Node.js installation in Ubuntu:

>> curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
>> sudo apt-get install -y nodejs
>> sudo apt-get install -y build-essential

Install or update npm

>> sudo npm install --version

Install node packages

>> cd 'project directory'
>> npm install express express-fileupload stylus morgan nib request fs image-size
>> npm install jade

sudo npm install --version

Create an Python 2.7 Environment for the image quality and DR evaluations.

>> conda create -n env_name python=2.7

Activate environment

>> source activate env_name

Install requested packages

>> conda install theano=0.9.0
>> pip install keras==1.2.2
>> conda install flask
>> conda install PIL scikit-learn scikit-image h5py

Open two screens on terminal, then run the Python server in Flask and the Node.js server

Open the first screen, then:

>> cd 'project directory'
>> cd python
>> cd source actvate env_name
>> python imageeval.py

Open the second screen, then:

>> cd 'project directory'
>> node app.js
