Multiview Extended Video with Activities (MEVA) Dataset README
|
||
|
||
1.0 Overview
|
||
|
||
The MEVA dataset was collected as part of the Intelligence Advanced
|
||
Research Projects Activity (IARPA) DIVA program
|
||
(https://www.iarpa.gov/index.php/research-programs/diva). It is
|
||
designed to support performers on the DIVA program and the broader
|
||
research community focused on activity detection in data from
|
||
simultaneous, multi-camera environments.
|
||
|
||
The data was collected using a variety of commercial, off-the-shelf
|
||
cameras to replicate equipment used in typical real-world
|
||
environments. The data may therefore include irregularities not seen
|
||
in high-end, research-grade video data. Further, there has been no
|
||
post-processing to the data with the exception of rotating data from
|
||
camera G639.
|
||
|
||
2.0 Directory Structure & Filenames
|
||
|
||
The directory organization follows a “video”/facility/date/hour/video
|
||
clip structure. Video files are typically five minutes in length, and
|
||
filenames have the following structure:
|
||
|
||
YYYY-MM-DD.timestamp-start.timestamp-end.camera-location.camera-number.
|
||
|
||
For example, file 2018-03-07.16-50-00.16-55-00.admin.G329.avi was:
|
||
* Recorded on March 7, 2018 starting at 16:50:00.
|
||
* Recording ends at 16:55:00.
|
||
* The camera was located in/on the admin building (see metadata, below).
|
||
* The camera number was G329.
|
||
|
||
The video data is organized into a four-level hierarchy of facility
|
||
id, date, then hour, then videos. Data was recorded on several NAS
|
||
units whose clocks were synchronized via GPS. The NAS software was
|
||
configured to record five-minute clips; however, clips do not all
|
||
necessarily start or stop on even five-minute boundaries. A few clips
|
||
may be shorter than five minutes due to transmission errors.
|
||
|
||
3.0 MEVA Known Facility Definitions
|
||
|
||
This 1.0 release of the MEVA dataset releases the MEVA Known Facility
|
||
set 1 (KF1). Various metadata, including a facility site map, camera
|
||
model information, and more are on this drive in the ‘doc/KF1’
|
||
directory.
