Abstract—In video surveillance, detection of moving objects from an image sequence is very important for target tracking, activity recognition, and behavior understanding. Background subtraction is a very popular approach for foreground segmentation
The vast accumulation of digital data requires new classes of applications that inmpact a computer user's life.We are investigating computing platforms that can deliver enough performance for these future workloads to enable their use in mass-market
Surveillance systems such as object tracking and detection systems typically rely on a single modality of color video for their input. These systems work well in controlled conditions but often fail when low lighting, shadowing, smoke, dust or unsta
Most video surveillance systems require to manually set a motion detection sensitivity level to generate motion alarms. The performance of motion detection algorithms, embedded in closed circuit television (CCTV) camera and digital video recorder (D
This paper presents a survey of trajectory-based activity analysis for visual surveillance. It describes techniques that use trajectory data to define a general set of activities that are applicable to a wide range of scenes and environments. Events
Surveillance systems are important technological tools that enable monitoring environments of interest and detecting potential malicious activities. In a world of increasing crime rates, wars, terrorism attacks, and security breaches, video surveill
