Abstract: This paper deals with the temporal synchronization of videos representing the same dynamic event from different viewpoints. We propose a novel approach to automatically synchronize such videos based on temporal self-similarities of sequences. We explore video descriptors which capture the structure of video similarity over time and remain stable under viewpoint changes. We achieve temporal synchronization of videos by aligning such descriptors by Dynamic Time Warping. Our approach is simple and does not require point correspondences between views while being able to handle strong view changes. The method is validated on two public datasets with controlled view settings as well as on other videos with challenging motions and large view variations.
