OCTAB: Online Crowdsourcing Tool for Annotations of Behaviors in Videos
Octab is a web-based annotation tool that allows precise and convenient annotations of micro events or behaviors in videos, which can be used directly with Amazon Mechanical Turk. It has been shown that crowdsourcing with OCTAB can be an effective method for obtaining high-quality micro-level behavior annotations in videos.
