Digital Image Processing Techniques for Restoring Old Damaged Films and Their Applications to Korean Film Restoration

摘要

This paper presents a set of digital image processing techniques for restoring old damaged Korean films. This project was initiated last year by joint efforts of Chung-Ang University, HFR, and Seoul National University supported by Korea Creative Content Agency (KOCCA). The characteristics and types of damages in old Korean films are quite different from those of the Hollywood films that have been properly stored and maintained. Therefore the need to develop a restoration solution for old damaged Korean films has become an issue of great interest. The set of image processing algorithms in the solution include; image stabilization, auto-focusing, and frame interpolation. This paper presents the characteristics of old Korean films and experimental results of the restoration using the proposed image processing solution. From the experimental results, it is evident that the visually acceptable level. The auto-focusing and the stabilization can improve the quality of damaged films up to.
