Valence/Arousal Online Annotation Tool

  

This tool, written in Python as a Flask application backed with a MongoDB, allows any number people to annotate video clips per-frame, for valence and arousal, remotely. In addition it can be easily extended to handle more annotations (e.g. discrete emotions).
 
The tool is open source and can be obtained on github, along with instructions.
