Audio-visual database

The University of Sheffield and INRIA have gathered synchronized auditory and visual datasets for the study of audio-visual fusion. The idea was to record a mix of scenarios where the audio-visual tasks of tracking the speaking face, where either the visual or auditory cues add disambiguating information; or more varied scenarios (eg. sitting in at a coffee break meeting) with a large amount of challenging audio and visual stimuli such as multiple speakers, varied amount of background noise, occulting objects, faces turned away and getting obscured, etc. Central to all scenarios is the state of the audio-visual perceiver and we have been very interesed in getting hold of some data recored with an active perceiver, so we propose that the perceiver is either static, panning or moving (probably limited to rotating its head) so as to mimic attending to the most interesting source at the moment. The calibrated data collection is freely accessible for research purposes at

4D repository ( )

This website hosts dynamic mesh sequences reconstructed from images captured using a multi-camera set up. Such mesh-sequences offer a new promising vision of virtual reality, by capturing real actors and their interactions. The texture information is trivially mapped to the reconstructed geometry, by back-projecting from the images. These sequences can be seen from arbitrary viewing angles as the user navigates in 4D (3D geometry + time) . Different sequences of human / non-human interaction can be browsed and downloaded from the data section. A software to visualize and navigate these sequences is also available for download.
