Activities and Tasks
List of Activities per Task
The table below provides a summary of the activity list and the required objects for the ActEV evaluations. The twelve target activities are used in the 1.A evaluation while nineteen target activities are used in both the ActEV Leaderboard and ActEV 1.B evaluations. The target objects for the ActEV evaluations (1.A, Leaderboard, and 1.B) are P={Person} and V={Construction_Vehicle, Vehicle}.

Different Tasks for the ActEV Evaluation
For the 1A Leaderboard evaluation, we evaluated for the
following two tasks: 1) Activity Detection (AD), and 2) Activity
and Object Detection (AOD). Each task can be completed
independently. For the TRECVID 2018 1.B ActEV evaluation we add the
following task Activity and Object Detection and Tracking
(AODT)
Activity Detection (AD)
For the Activity Detection task, given a target activity, a system automatically detects and temporally localizes all instances of the activity. For a system-identified activity instance to be evaluated as correct, the type of activity must be correct and the temporal overlap must fall within a minimal requirement as described in Evaluation Plan.
Activity and Object Detection (AOD)
For the Activity and Object Detection task, given a target activity, a system detects and temporally localizes all instances of the activity and spatially detects/localizes the people and/or objects associated with the target activity. For a system-identified instance to be scored as correct, it must meet the temporal overlap criteria for the AD task and in addition meet the spatial overlap of the identified objects during the activity instance as described in the Evaluation Plan.
Activity Object Detection and Tracking (AODT) (for
the 1B evaluation)
For the Activity Object Detection and Tracking task, given a target activity, a system detects and temporally localizes all instances of the activity, spatio-temporally detects/localizes the people and/or objects associated with the target activity, and properly assigns IDs the objects play in the activity. For a system-identified instance to be scored as correct, it must meet the temporal overlap criteria and spatio-temporal overlap of the objects for the AOD task and correctly assign the IDs to the objects as prescribed in the activity definition as described in the Evaluation Plan.
TRECVID ActEV 2018 1B Evaluation
Summary
The ActEV evaluation sought to evaluate
robust automatic activity detection algorithms for a multi-camera
streaming video environment. ActEV is an extension of the annual
TRECVID Surveillance Event Detection (SED) evaluation by adding a
large collection of multi-camera video data. Some of the
applications of activity detection of interest are public safety
and traffic monitoring and management. ActEV addressed activity
detection for both forensic applications and for real-time
alerting. The ActEV evaluation was initially run as a blind
evaluation and is currently open as a leaderboard evaluation.
Participants may join the leaderboard evaluation independent of
participation in the blind evaluation.
What is Activity Detection in Videos ?
By activity detection, we mean to detect
visual events (people engaged in particular activities) in a large
collection of streaming video data.
What
The ActEV evaluation is being conducted to
assess the robustness of automatic activity detection for a
multi-camera streaming video environment.
Who
NIST invites all organizations, particularly
universities and corporations, to submit their results using their
technologies to the ActEV evaluation server. The evaluation is open
worldwide. Participation is free. NIST does not provide funds to
participants.
How
To take part in the ActEV evaluation you
need to email and register on the actev.nist.gov website. We
then send you information on how to download data and how to create
an account on the ActEV scoring server (see website for details).
Using a valid registered account, you are able to upload your
JSON format results (see website for: Evaluation Plan) to the ActEV
scoring server and participate in the ActEV evaluation. The ActEV
evaluation is currently running as a leaderboard
evaluation.
Why
The primary driver of the evaluation is to
support public safety and traffic monitoring and management by
automatic activity detection in streaming video.
Data
The ActEV data used for this evaluation is
an unreleased portion of the VIRAT dataset. The data was
provided in MPEG-4 format. (please send an email to receive
information: Data download, Licensing and Participation Agreements,
and Evaluation Plan).
Metrics
The main scoring metrics was based on
detection, temporal localization and spatio-temporal localization.
We used standard evaluation measures (e.g., probability of
missed detection, rate of false alarm) (see: Evaluation
Plan).

Rules for Leaderboard Evaluation
Schedule
TRECID ActEV 2018 You can submit maximum of
2 results per day and maximum of 50 results in total for AD and
AOD.
The challenge participant can train their systems
or tune parameters using any data complying with applicable laws
and regulations. In the event that external limitations preclude
sharing such data with others, participant are still permitted to
use the data, but they must inform NIST that they are using such
data, and provide appropriate detail regarding the type of data
used and the limitations on distribution.
The challenge participant agree not to probe the
test videos via manual/human means such as looking at the videos to
produce the activity type and timing information from prior to the
evaluation period to end of leaderboard evaluation.
All machine learning or statistical analysis
algorithms must complete training, model selection, and tuning
prior to running on the test data. This rule does not preclude
online learning/adaptation during test data processing so long as
the adaptation information is not reused for subsequent runs of the
evaluation collection.
The only VIRAT data that may be used by the
systems are the ActEV provided training and validation sets,
associated annotations, and any derivatives of those sets (e.g.
additional annotations on those videos). All other VIRAT data and
associated annotations may not be used by any of the systems for
the ActEV Leaderboard Evaluation.
