Real-time Motion Picture Restoration

Remi J. Gurski

Through age or misuse, motion picture films can develop damage in the form of dirt or scratches which detract from the quality of the film. Removal of these artifacts is a worthwhile process as it makes the films more visually attractive and extends the life of the material. In this thesis, various methods for detecting and concealing the effects of film damage are described. Appropriate algorithms are selected for implementation of a system, based on a TMS320C80 video processor, which can remove the effects of film defects using digital processing. The restoration process operates in real-time at video frame rates (30 frames per second). Details of the software implementation of this system are presented along with results from processing damaged film material. The effects of damage are significantly reduced after processing.
