1. A processor-implemented method, the method comprising:
acquiring a feature map of a template image, a color histogram of a foreground of the template image, and a color histogram of a background of the template image other than the foreground, where the foreground includes an object included in the template image;
acquiring a feature score map, and a bounding box map corresponding to the feature score map, based on the feature map of the template image and a feature map of a search image of a current frame;
acquiring a color score map based on the color histogram of the foreground, the color histogram of the background, and a color value of the search image of the current frame;
acquiring a final score map, and a bounding box map corresponding to the final score map, based on the feature score map, the color score map, and the bounding box map; and
outputting a bounding box corresponding to a pixel having a highest value of the final score map from the bounding box map.
