ScaleAPI - Image Annotation MVP

Setup

I assume you have Ubuntu 14.04

Install Node

curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -
sudo apt-get install -y nodejs

Install MongoDB

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927
echo "deb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list
sudo apt-get update
sudo apt-get install -y mongodb-org

Clone the repository

git clone https://github.com/JohnnyJohnAndTheFunkyBunch/imgbox.git

Then install the packages and run server.js

npm install
node server.js

Using the web app

The server should be served on port 80. You can then open the web app through [your ip address]:80 and it should look something like this:

Using the annotation API entry point

Just like the real ScaleAPI, you curl using these parameters:

curl "http://[your ip address]/api/task/annotation" \
  -u YOUR_API_KEY: \
  -d callback_url="http://www.example.com/callback" \
  -d instruction="Draw a box around each baby cow and big cow." \
  -d attachment_type=image \
  -d attachment="http://i.imgur.com/v4cBreD.jpg" \
  -d objects_to_annotate="baby cow" \
  -d objects_to_annotate="big cow" \
  -d with_labels=true
