METHOD AND APPARATUS FOR DETECTING LEFT OBJECTS
Document Type and Number:
WIPO Patent Application WO2005125003
Kind Code:
A3
Abstract:
A method and apparatus for detecting objects (e.g., bags, vehicles, etc.) left in a field of view are disclosed. A long-term representation (104) and a short-term representation (106) of the field of view are constructed, and a difference (108) between the long-term representation and the short-term representation is calculated. One or more criteria may optionally be applied to this difference to determine whether the difference represents an object that was left in the field of view.
