1. A processor-implemented method with object tracking, the method comprising:
performing, using a first template image, forward object tracking on first image frames in a first sequence group;
determining a template candidate image of a second template image for second image frames in a second sequence group;
performing backward object tracking on the first image frames using the template candidate image;
determining a confidence of the template candidate image using a result of comparing a first tracking result determined by the forward object tracking performed on the first image frames and a second tracking result determined by the backward object tracking performed on the first image frames;
determining the second template image based on the confidence of the template candidate image; and
performing forward object tracking on the second image frames using the second template image, including, in response to the confidence of the template candidate image being less than or equal to a preset threshold, discarding the second template image and continuously using the first template image in performing forward object tracking on the second image frames in the second sequence group,
wherein the confidence of the template candidate image is determined based on a degree of overlap between at least one of corresponding pairs obtained from the first tracking result and the second tracking result.
