Efficient Digital Image Restoration for Analog Video Tape Archives
This paper introduces a research project, which addresses problems associated with the image restoration process for digitization and archiving of analog video tapes. The goal of this work is the development of a new model of image restoration and its application to real video sequences. This research will focus primarily upon the digital imaging and restoration process chain; its main thrust will be the removal of real-world distortion effects. The research will also include a refinement of common image restoration strategies. A preliminary survey of user experience with analog tapes has given some insights into how to set up a new restoration process, and it has highlighted opportunities to define a ranking of issues to be solved within this framework. The main effects of image degradation, sources and constraints are presented within this paper.
