Video synchronization using bit rate profiles
We present a novel approach for the temporal synchronization of multiple videos which is based on cross-correlating bit rate profiles. The proposed scheme determines the temporal offset without major restrictions on viewing angles, camera properties and camera motion. We propose two extensions of the basic algorithm which reduce the influence of camera motion and distracting background objects. Additionally, we describe how to optimally combine different bit rate components in order to further improve the reliability of the synchronization scheme. The proposed approach, when combined with the three extensions, leads to a reliable, robust, and frame accurate temporal alignment of videos at remarkably low complexity.
