Title: Abnormal Behaviors Detection in Surveillance Video
Background: Abnormal behaviors in public space can
be potentially hazardous. For example, crowd congestion may
cause a stampede if the density is too high, and panic
dispersing often implies an emergent situation. Ordinary
approach to handle the surveillance video from the publicly
installed cameras is to arrange human operators by
monitoring screens. However, its performance is greatly
impacted by the fatigue and distraction. On the other hand,
the information distribution of surveillance data is often
very sparse. To reveal the crucial information, analyst must
inspect the entire video which is extremely time consuming.
Therefore, a computer vision-based approach to effectively
detect the anomalies can be exploited to address the
Data: (1) Bench-marking datasets: KTH, UCF and Weizmann
(2) Provided dataset: 440 clips of videos, with 9 categorizes of
behaviors including sabotaging public properties, shooting, holding
blades, fist fights, robbery, flee, thievery, assault and normal
Task: To devise an approach to recognize the
individual/crowd behaviors with either conventional-based or deep
learning-based techniques. The proposed approach should provide
satisfactory performance on behavior classification or anomaly
detection, which can be utilized for the prediction of potentially
hazards and video abstraction. The approach should have a good
precision on the bench-marking datasets, and show promising
effectiveness on the provided behavior dataset to prove its
robustness on variable data qualities.
Participants can be either university students, graduated
researchers or from industries.
One team can include 1-3 team members, and 1-2 advisers.
Participants need to provide source codes, trained model,
algorithm description and testing results.
The performance of the proposed approach is evaluated by the
accuracy on both benchmarking and provided datasets.
