Classifying tracked objects in far-field video surveillance
… detected and tracked in a variety of far-field video sequences, captured by a static, uncalibrated camera. We introduce the use of scene-specific context features (such as image-position of objects) to improve classification performance in any given scene. At the same time, we design a …

Graph-based Approach for Anomaly Detection in Video Surveillance
… safety and security. Human operators of modern surveillance systems are confronted with a huge amount of digital video data that needs to be monitored constantly. However, due to many limitations such as fatigue and time efficiency, human operators are not continuously watching these …

Detection and representation of moving objects for video surveillance
… moving objects (such as people and vehicles) in video surveillance sequences. The first technique analyses the original video and exploits spatial and temporal information to find those pixels in the images that correspond to moving objects. The second technique analyses video sequences that have …

Student, parent, and teacher attitudes toward video surveillance monitoring
… documented. In response, some schools employ video surveillance cameras (VSCs) in their hallways. Student, parent, and teacher perceptions of video surveillance monitoring are essentially unknown. This study examines the effect, if any, of the presence of video surveillance cameras in schools. …

Re-identification and semantic retrieval of pedestrians in video surveillance scenarios
… task, named semantic retrieval of pedestrians in video surveillance scenarios, which consists of searching images of individuals using a textual description of clothing appearance as a query, given by a Boolean combination of predefined attributes. This can be useful in applications like forensic …

Virtual pan-tilt-zoom for a wide-area-video surveillance system
… low cost. The availability of high-pixel count video imaging systems that can cover a wide field-of-view enables a surveillance technique called Virtual Pan-Tilt-Zoom. Virtual Pan-Tilt-Zoom provides the same functional properties as a mechanical pan-tilt-zoom setup, but it does not suffer from …
