Abstract

Many algorithms have been proposed in literature for digitalfilm restoration; unfortunately, none of them ensures a perfectrestoration whichever is the image sequence to be restored.Here, we adopt an approach to digital scratch restoration based on the combination of relatively well settled distinct techniques. We propose P-LSR, a parallel version focusing on strategies based on both task and data partitioning to achieve good load balancing, that well adapts also to be distributed. Parallel performance is deeply investigated for several real image sequences.
