Contents I. Introduction
The idea about problem of abandoned luggage detection was established by Sugrue and Davies in around 2005 [Sugrue and Davies 2005]. Then, there are many techniques and systems were proposed to solve this problem until present. For example Kevin et al. [Kevin et al. 2006] proposed the Macov Chain Monte Carlo tracking (MCMC). Guler et al. [Guler et al. 2007] proposed the Motion History Tracking. The system of alarming and finding the owner of left baggage was proposed by Chang et al.[Chang et al. 2010].
