Classification: CPC H  G | IPC G  H

Claim 10:
11. An apparatus for determining a duration and at least a region of interest for managing an event, the apparatus comprising:
a memory in communication with a processor, the memory storing a computer program recorded therein, the computer program being executable by the processor to cause the apparatus at least to:
determine a set of coordinates each for two or more appearances of a target subject within a sequence of images, the set of coordinates of the two or more appearances of the target subject defining a first path;
determine a set of coordinates each for two or more appearances of a related subject within a sequence of images, the related subject relating to the target subject, the set of coordinates of the two or more appearances of the related subject defining a second path;
determine one or more minimum distances between the first path and the second path so as to determine at least a region of interest;
determine a timestamp of a first appearance and a timestamp of a last appearance of the target subject; and
determine a timestamp of a first appearance and a timestamp of a last appearance of the related subject when it is determined that at least one of the one or more minimum distances between the first path and the second path is within a predetermined distance so as to determine a duration of interest.
