Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.


What things you need to install the software and how to install them

Tensorflow 1.12
Tensorflow Object Detection 

Installing Prerequisites

A step by step series of examples that tell you how to get a development env running. Open an issue if you get any problem installing below mentioned requisites

Install TensorFlow version 1.12

pip install tensorflow==1.12

Install TensorFlow GPU version 1.12

pip install tensorflow-gpu==1.12

Clone tensorflow/models

git clone

Install Protobuf

Make sure you grab the latest version
curl -OL

unzip -d protoc3

Move protoc to /usr/local/bin/
sudo mv protoc3/bin/* /usr/local/bin/

Move protoc3/include to /usr/local/include/
sudo mv protoc3/include/* /usr/local/include/

Optional: change owner
sudo chown $USER /usr/local/bin/protoc
sudo chown -R $USER /usr/local/include/google

Install Flask

pip install flask

End with an example of getting some data out of the system or using it for a little demo

Running the system

Clone our repository

git clone

Copy the contents of repository in (replace in utils folder)


Open terminal in objectdetection folder and run


Finally, open localhost:5000 in browser and write in air...

How it works

  1. Show one finger and write a word.
  2. Show two fingers to predict the air written word.
  3. Show three fingers to give a space.
  4. Show four fingers to enter prediction mode and then show n fingers to add nth selection.
  5. Show five fingers for backspace.
