OVERVIEW

BAUM-1 (Bahçeşehir University Multimodal Affective Database - 1) is a collection of audio-visual facial clips of acted and spontaneous (re-acted) affective expressions. The audio-visual clips have been recorded from 31 subjects, who express a rich set of emotional and mental states in an unscripted way in Turkish. The database contains synchronous facial recordings of subjects with a frontal stereo camera and a half profile mono camera.

The subjects first watch visual or audio-visual stimuli on a screen in front of them, which are designed and timed to elicit certain emotions and mental states. The subjects answer questions about the visual stimuli in their own words. The target emotions that we want to elicit are the six basic ones (happiness, anger, sadness, disgust, fear, surprise) and additionally boredom and contempt. We also aim to elicit several mental states including being unsure (including confusion, undecidedness), being thoughtful, concentration, interest (including curiosity), and bothered (inc. complaint). The database also contains short acted recordings of each subject. The video clips have been categorically annotated by five labelers. Also a score between 0-5 is given to each video clip indicating the activation level at the peak frame of the emotion or mental state expressed in the video clip.
