Abstract (en)

[origin: GB2333413A] Archived or other defective video signals are restored in two processing rounds. First, global or block motion vectors are identified and used to remove unsteadiness and brightness flicker. Then, motion vectors are identified in the steadied and flicker-free signal and assigned to pixels. These pixel motion vectors are then used in motion compensated noise reduction, scratch removal and dirt concealment.
