Automatic annotation of head velocity and acceleration in Anvil

Research output: Chapter in Book/Report/Conference proceedingArticle in proceedingsResearchpeer-review


We describe an automatic face tracker plugin for the ANVIL annotation tool. The face tracker produces data for velocity and for acceleration in two dimensions. We compare the annotations generated by the face tracking algorithm with independently made manual annotations for head movements. The annotations are a useful supplement to manual annotations and may help human annotators to quickly and reliably determine onset of head movements and to suggest which kind of head movement is taking place.
