Abstract

Software-based grouping of multiplexed video based on video content, as opposed to the signal generated by multiplexers, is described. The method is based on energy minimization approach. The algorithm automatically determines the amount of multiplexed camera views, and then the frames are grouped with respect to camera views. The algorithm is free of any threshold differences between camera views, and does not depend on the presence of quiet zones. The method also compensates for interference noise, local and global motion, are contrast changes.
