Restoration of Damaged Korean Films by Using Various Image Processing Techniques

Recently, the digital cinema distribution chain takes an additional path for old, damaged films with proper restoration. Old films, which are acquired by a low-quality camera and stored in harsh condition, tend to have lot of defects compared with modern digital cinemas. This paper presents a set of image processing algorithms for enhancing and restoring old films severely degraded by camera jitters, film scratches, grain noise and poor contrast, to name a few. In 2005, Korean Film Council re-ran 30 years old animated films in digital, high standard quality. In this work we briefly introduce the restoration of the animation film, and provide additional, ongoing restoration works for old Korean film with consideration of the bottleneck between the main workflow and the intermediate equipment compatibility. Experimental results will be presented for restored samples of old movies and animations followed by the workflow pipeline of the proposed restoration module.
