Abstract
Line scratches are common degradations in motion picture films. This paper presents an efficient method for line scratches detection strengthened by a Kalman filter. A new interpolation technique, dealing with both low and high frequencies (i.e. film grain) around the line artifacts, is investigated to achieve a nearby invisible reconstruction of damaged areas. Our line scratches detection and removal techniques have been validated on several film sequences. 1 Introduction Motion picture industry is 100 years old and chemical film (nowadays polyester, former triacetate or nitrate) is still the main support for motion picture film, despite of fast-growing digital media. It is a fact the film and dye coating for color are not stable over decades. In addition, some old films are reassembled from fragments scattered over various libraries and archives. Only digital processing will ensure the removal of the various artifacts due to age and a well balanced output to a film recorder. The ma...
