Detecção de Roubo de Computadores em Laboratório Usando Visão Computacional

Computer theft in computer labs causes academic damage to courses that require this resource and ends up directly harming students. In this context, this paper describes a methodology applied to detect computer removal through video analysis in real-time. For each frame, image processing and computer vision techniques were used, subtracting background information, binarization, segmentation of the region of interest and definition of contours. The case study was developed at a Brazilian university. For theft detection, it was considered a black computer tower case carried by people leaving the laboratory. Monitoring is carried out by a camera positioned in front of the lab exit door. The software developed alerts a suspicious activity that may indicate a possible computer theft.
