Individual tracking of objects in the video such as people and the luggages they carry is important for surveillance applications as it would enable deduction of higher level information and timely detection of potential threats. However, this is a challenging problem and many studies in the literature track people and the belongings as a single object. In this thesis, we propose using thermal band video data in addition to the visible band video data for tracking people and their belongings separately for indoor applications using their heat signatures. For object tracking step, an adaptive, fully automatic multi object tracking system based on mean-shift tracking method is proposed. Trackers are refreshed using foreground information to overcome possible problems which may occur due to the changes in object’s size, shape and to handle occlusion, split and to detect newly emerging objects as well as objects that leave the scene. By using the trajectories of objects, owners of the objects are found and abandoned objects are detected to generate an alarm. Better tracking performance is also achieved compared a single modality as the thermal reflection and halo effect which adversely affect tracking are eliminated by the complementing visible band data.

Mean-Shift Tracking for Surveillance Applications Using Thermal and Visible Band Data Fusion Beyan, Cigdem; Temizel, Alptekin (2011-04-28) Separate tracking of objects such as people and the luggages they carry is important for video surveillance applications as it would allow making higher level inferences and timely detection of potential threats. However, this is a challenging problem and in the literature, people and objects they carry are tracked as a single object. In this study, we propose using thermal imagery in addition to the visible band imagery for tracking in indoor applications (such as airports, metro or railway stations). We u...
Object Extraction and Classification in Video Surveillance Applications Civelek, Muhsin; Yazıcı, Adnan (2017-05-01) In this paper we review a number of methods used in video surveillance applications in order to detect and classify threats. Moreover, the use of those methods in wireless surveillance networks contributes to decreasing the energy consumption of the devices because it reduces the amount of information transferred through the network. In this paper we focus on the most popular object extraction and classification methods that are used in both wired and wireless surveillance applications. We also develop an a...
Object tracking system with seamless object handover between stationary and moving camera modes Emeksiz, Deniz; Temizel, Alptekin; Department of Information Systems (2012) As the number of surveillance cameras and mobile platforms with cameras increases, automated detection and tracking of objects on these systems gain importance. There are various tracking methods designed for stationary or moving cameras. For stationary cameras, correspondence based tracking methods along with background subtraction have various advantages such as enabling detection of object entry and exit in a scene. They also provide robust tracking when the camera is static. However, they fail when the ...
Surveillance Video Querying With A Human-in-the-Loop STONEBROKER, MICHAEL; Bhargava, Bharat; Cafarella, Michael; COLLINS, ZACHARY; McClellan, Jenna; SIPSER, AARON; Sun, Tao; NESEN, ALİNA; SOLAIMAN, K.M.A.; MANI, GANAPATHY; Kochpatcharin, Kevin; Kochpatcharin, Kevin; Angın, Pelin; MACDONALD, JAMES (2020-06-19) SurvQ is a video monitoring system appropriate for surveillance applications such as those found in security and law enforcement. It performs real time object property identification and stores all data in a scalable DBMS. Standing queries implemented as database triggers are supported. SurvQ contains novel adaptive machine learning and algorithmic property classification. The application of SurvQ to assist the West Lafayette (IN) police department at identifying suspects in video is described. This paper a...
Optimal data compression for lifetime maximization in wireless sensor networks operating in stealth mode Incebacak, Davut; Zilan, Ruken; TAVLI, BÜLENT; Barcelo-Ordinas, Jose M.; Garcia-Vidal, Jorge (2015-01-01) Contextual privacy in Wireless Sensor Networks (WSNs) is concerned with protecting contextual information such as whether, when, and where the data is collected. In this context, hiding the existence of a WSN from adversaries is a desirable feature. One way to mitigate the sensor nodes' detectability is by limiting the transmission power of the nodes (Le., the network is operating in the stealth mode) so that adversaries cannot detect the existence of the WSN unless they are within the sensing range of the ...
