Outline of Final Research Achievements

In addition to respective noise suppression processing for blotches, scratches, flicker, and irregular frame shake, developed previously by the author, noise suppression processing for focus micro-variations was developed. An integrated noise suppression system for age-deteriorated film that integrates all of these was created. Additionally, noise suppression processing for consumer video images was developed with improvements based on the above-mentioned integrated noise suppression processing, and a video-dedicated noise suppression system created. Applying these two systems to digital video images obtained by digitizing actual age-deteriorated film and VHS tape yielded excellent noise removal effects in a practical amounts of processing time.
