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:
29 April 2020: We've updated the video data to remove a block of 130 corrupted videos for the G328 camera, and to rotate all 83 instances of the G639 camera. See Section 3.1 of the MEVADATA readme for more details.
19 March 2020: We've released GPS data associated with the actors in the released video. See here for details.
13 December 2019: We're pleased to announce annotations for an addition 6 hours of MEVA data, resulting in 22 hours of annotated data. Annotations are available via the git repository.

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.

Releases

Known Facility Release #1 ("KF1"):

The KF1 data was collected over a total of three weeks at the Muscatatuck Urban Training Center (MUTC) 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.

The actors were also carrying GPS loggers; see here for more details.

MEVA data git repository

The MEVA data git repository is an evolving collection of metadata and annotations released for the MEVA KF1 data. Highlights include:

Metadata

Annotations

A subset of the MEVA KF1 data has been annotated for the activities defined in the NIST ActEV Challenge. There are annotations for 22.1 hours (266 five-minute video clips) of data. The released annotations were generated by the same workflow used to produce the sequestered annotations used on the ActEV Sequestered Data Leaderboard. Resources include:
