colortracker.js

This is an example of using the computer vision algorithms and techniques that are provided by tracking.js in the NodeJS environment, rather than in its intended browser environment.

Install

This code has been tested on Ubuntu 16.04, with NodeJS v8.x. It likely works elsewhere and with other NodeJS versions, but you're in uncharted territory if you go there.

• Install NodeJS

curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
sudo apt-get install -y nodejs

• Clone this repository

• Install dependencies

cd colortracker-example
npm install

Run

nodejs colortracker.js

The program looks for yellow objects, and prints the attributes of the bounding rectangles it calculates for those objects.

For comparison and to help visualize what these bounding rectangles represent, it would be useful to run the browser-based code as described at tracking.js.
