Formalization of People and Crowd Detection and Tracking for Smart Video Surveillance
One of the promising areas of development and implementation of artificial intelligence is the automatic detection and tracking of moving objects in video sequence. The paper presents a formalization of the problem of detection and tracking of people and crowd in video. At first, we defined person, group of persons and crowd motion detection types and formalized them. For crowd, we defined three main types of its motion: direct motion, aggregation and dispersion. Then, we formalised the task of tracking for these three groups of people (single person, group of persons and crowd). Based on these formalizations, we developed algorithms for detection and tracking people and crowd in video sequences for indoor and outdoor environment. The results of experiments for video sequences obtained using a stationary and moving video camera are presented
Detection of traffic anomalies for a safety system of smart city
For modern smart city with sustainable development we need to provide reasonable
level of safety and efficient management of the resources. Instant response to incidents and
abnormal situations will help to provide such high bars for city residents, which requires
deployment of application of intelligent information processing and data analytics into
infrastructure. Closed-circuit television (CCTV) is playing a key part in assurance of city
security - most of the modern large cities equip with powerful monitoring systems and
surveillance cameras. Video data covers most of the city and could be efficiently used to find
anomalies or trends. This hard task for non-stop video monitoring could be solved by modern
achievements in machine learning and computer vision techniques, which can automate the
process of video analysis and identify anomalies and incidents without human intervention. In
this paper, we used computer vision methods like object detection and tracking, as well as
neuron networks for classification and detection of anomalies on real time video. As a result of
this work we suggested the working approach for detection of vehicle/pedestrian violating
legal trajectory anomaly, which we tested on real-time video provided by surveillance cameras
