Abstract
A technique is provided for calculating the time offsets between different video cameras and re-synchronizing the captured frames in a post-processing manner, thus eliminating the necessity of an explicit common clock for synchronization. This approach allows effective synchronization of frames from different cameras so that a multi-camera system can be used to more accurately analyze a subject under observation.
