The Multiview Extended Video with Activities (MEVA) dataset

The large-scale MEVA dataset is designed for activity detection in multi-camera environments. It was created on the Intelligence Advanced Research Projects Activity (IARPA) Deep Intermodal Video Analytics (DIVA) program to support DIVA performers and the broader research community.

NEWS: 6 Nov 2019: We're pleased to announce the release of 4.6 hours of UAV data! See the UAV data readme for more details.

About MEVA data

MEVA aims to build a corpus of activity video collected from multiple viewpoints in realistic settings.

There is a MEVA data users Google group to facilitate communication and collaboration for those interested in working with the data. Join the conversation through the meva-data-users group.


Known Facility Release #1 ("KF1"):

The KF1 data release contains approximately 254 hours of ground camera video and an additional 4.6 hours of UAV video, collected at the Muscatatuck Urban Training Center with a team of over 100 actors performing in various scenarios. The fields of view, both overlapping and non-overlapping, capture person and vehicle activities in indoor and outdoor environments. There were multiple realistic scenarios with a variety of scripted and non-scripted activities.

The camera infrastructure included commercial-off-the-shelf EO cameras; thermal infrared cameras as part of several IR-EO pairs; two DJI Inspire 1 v2 drones, and a range of still images from handheld cameras.

Additional resources such as a facility site map, camera model information, and camera calibration models will be also be released.

The video to the right is a montage of randomly selected KF1 clips, re-encoded for faster playback.
