Abandoned luggage represents a potential threat to public safety. Identifying objects as luggage identifying the owners of such objects and identifying whether owners have left luggage behind are the three main problems requiring solution. This paper proposes two techniques which are foreground-mask sampling to detect luggage with arbitrary appearance and selective tracking to locate and to track owners based solely on looking only at the neighborhood of the luggage. Experimental results demonstrate that once an owner abandons luggage and leaves the scene the alarm fires within few seconds. The average processing speed of the approach is frames per second which is sufficient for real world applications. 1. Introduction Intelligent and automatic security surveillance systems have recently become an active research focus due to continuously growing public demand for such systems. Terrorist attacks frequently employ bombs such as car bombs suicide bombs and luggage bombs. Modern technology cannot fully prevent such attacks and security officers can easily miss their targets. However compared with the two previous forms luggage bombs are relatively
