Workpackage 9 Grid-enabled Scientific Libraries Parallel and Distributed Film Line Scratch Restoration by Fusion Techniques

Many algorithms have been proposed in literature for digital film restoration; unfortunately, none of them ensures a perfect restoration whichever is the image sequence to be restored. Here, we propose an approach to digital scratch restoration based on image fusion techniques for combining relatively well assested distinct techniques. The method has large memory requirements and is computationally intensive; due to this main reason, we propose parallel versions of the restoration approach, focusing on strategies based on data partition and pipelining to achieve good load balancing. The parallel approach well adapts also to be distributed.
