The MPI Emotional Body Expressions Database for Narrative Scenarios

Ekaterina Volkova, Stephan de la Rosa, Heinrich H. Bülthoff, Betty Mohler, Marko Nardini
2014 PLoS ONE  
We report the results of physical motion properties analysis and of an emotion categorisation study. The reactions of observers from the emotion categorisation study are included in the database.  ...  Moreover, many of these databases consist of video recordings which limit the ability to manipulate and analyse the physical properties of these stimuli.  ...  As a result of the classification study, as many as 85% of motion sequences have a unique modal value in the distribution of observers' categorisation.  ...
