Video Editor for Annotating Human Actions and Object Trajectories

A system for managing, annotating and editing video sequences is a necessary tool in research on recognition of human actions and tracking people or objects. In addition annotation process is complex and expensive, so some people try to use crowdsourced marketplace based tools to make this process cost effective. Such a tool, video editor for annotating human actions and object trajectories -VATRAC, is presented. It enables flexible viewing video sequences under selected configuration of annotation layers, adding and editing of annotations for actions and trajectories of the entire objects or selected parts of the objects. Video sequences can be queried according to a variety of criteria and preferences for example searching for subsequences annotated with the action class.
