Abstract: The European research project CineXPRES is focusing on improving the digitization, preservation, and restoration workflows for old film content. A central topic in this project is an attempt to define a practical quality assessment for digitized film content. The authors believe that there is no absolute measure of quality, but instead only measures dedicated to specific decision processes. To this end, three image quality estimators are defined, providing efficient tools in various situations that every archivist will have to face in the future: a multidimensional objective quality measure consisting of a collection of degradation estimators, a conditional subjective quality estimator taking the display into account, and a conditional objective quality estimator considering the ease of restoring content. This paper describes the computation of these estimators and reviews a few practical situations in which they provide answers to complex decision-making situations.

bio
François Helt has 30 years of experience in professional video and film, designing image processing software for audiovisual applications. He has been the research and development manager of teams dedicated to special effects software, including film scanners and film printers' drivers since 1991. Helt served as technical manager of the European project “Limelight,” aimed at the design of a complete digital film restoration system from 1994 to 1997. He is also founder and chief executive officer of DUST, a company specializing in digital restoration and processing of film from 1997 to 2002. — Helt designed the color conversion and calibration software for digital cinema from 2004 to 2006 as well as projection measurement systems. He is chief scientific officer of Highlands Technologies Solutions and its current interest include visual perception models and measurement theory.
