  • Efficient restoration of variable area soundtracks
    Hassaïne, Abdelâali ; Decencière, Etienne ; Besserer, Bernard
    The restoration of motion picture films using digital image processing has been an active research field for many years. The restoration of the soundtrack however, has mainly been performed in the ... sound domain, using signal processing methods, in spite of the fact that it is recorded as a continuous image between the images of the film and the perforations. In this paper a restoration method for variable area soundtrack restoration at the image level is presented. First, a novel method is proposed for the detection of the symmetry axis of the scanned soundtrack. Then, a comparison between thewatershed and the region growing segmentation of the soundtrack is developed. Another algorithm aiming to enforce the symmetry and to correct theedges of the segmented image is presented. A last step aiming to smooth theedges of the obtained image is performed. Finally, experimental results arereported and possible future improvements are discussed.
