Description in Proc. 5th IEEE Workshop on Applications of Computer Vision
A suitable detection/reconstruction approach is proposed for removing line scratches from degraded motion picture films. The detection procedure consists of two steps. First, a simple 1D-extrema detector provides line scratch candidates. Line artifacts persist across several frames. Therefore, to reject false detections, the detected scratches are tracked over the sequence using a Kalman filter. A new Bayesian restoration technique, dealing with both low and high frequencies around and inside the detected artifacts, is investigated to achieve a nearby invisible restoration of damaged areas. 1 Introduction Digital film restoration has only very recently been explored [11] [13][16][14][5][2][4] [9]. Up to now, old films have been restored using traditional film restoration techniques, like chemical baths or film polishing. However, such techniques do not permit the removal of all kinds of degradations. Computer-aided techniques have also been used to restore classic old films but they ...
