1. An object tracking system comprising:
at least one memory storing instructions; and
at least one processor configured to execute the instructions to perform:
generating, via a first detector implemented by the at least one processor, a first detection result of an object from a first image;
generating, via a second detector implemented by the at least one processor, a second detection result of the object from a second image, the second image being different from the first image;
generating tracking information for the object, the tracking information including appearance information which represents appearance of the object from cameras capturing the first image and the second image; and
controlling the first detector and the second detector based on the tracking information,
wherein controlling the first detector and the second detector comprises controlling the first detector to set a first searching area for searching the object in the first image and controlling the second detector to set a second searching area for searching the object in the second image, and wherein the at least one processor is further configured to execute the instructions to perform:
displaying the first searching area set by the first detector on the first image and displaying the second searching area set by the second detector on the second image.
