An interactive distributed environment for digital film restoration

Abstract

The paper presents FESR an interactive environment enabling collaborative digital film restoration over a digital network by connecting seamless the supervisor and operator's graphical frameworks, a parallel Image Processing server, a video stream server and a DBMS server. It allows a supervisor to remotely define the restoration protocol and to monitor job progress by using a metadata-driven navigation interface. The operators use a graphical desktop to interactively perform parameter steering of restoration filters and to activate and synchronize batch processing of defect detection and restoration filters on the IP server. The video stream server stages digital frames while the meta-data server stores defect masks and other film attributes by using MPEG7 formalism for video-segments representation. System prototype architecture, inspired to component technology is described. © Springer-Verlag 2004.
