Golden Years

Following the successful commercialisation of a software package to take all the scratches and clicks out of old recordings, the Signal Processing Group turned their attention to the task of renovating old videos and films in real time. Television channels, archivists and film producers all hold numerous archives which together make up a unique history of artistic and cultural development of all aspects of life in this century. Unfortunately, this archive material is subject to degradation that increases with each playing, until it eventually becomes unusable. For economic reasons, any system used for copying and restoring old films must be fast as well as effective. Such a system has now been produced under the 'Aurora' project, in partnership with the universities of Delft and Tampere.
