5.3.4.4 Missing Object
Missing object means the system will trigger alarm if it exceeds certain amount of time after the target is
taken away from the original scene.
The system can make statistics of the still areas in the foreground area and distinguish if it is missing
object or abandoned object according to the similarity between foreground and background, it will
trigger alarm when it exceeds the time which is set by users.
Because the system distinguishes abandoned object from missing object according to the similarity of
foreground and background, it may cause error between abandoned object and missing object in a
situation where both foreground and background are complicated.
