Abstract
A method for tracking an object in a low frame rate video is provided. Matching processes are performed between consecutive frames by using conversion feature maps acquired by converting each of features on feature maps of the consecutive frames into feature descriptors including each corresponding feature information and each corresponding location information, thereby allowing object tracking regardless of whether time interval per frame is long or short. The object tracking is performed by matching feature descriptors on a plurality of pyramid feature maps on an entire area of a next frame and feature descriptors on a plurality of cropped feature maps generated by cropping object areas extracted on a current frame, thereby allowing not only quick matching between the cropped areas and the entire area but also the increased accuracy due to no limitation of the feature searching area.
