Summary: Old motion pictures often present defects due to poor preservation conditions or to rudimentary shooting techniques. Damage may be so important that it considerably reduces the interest or the pleasure of watching them. Restoration of these films is necessary in order to recover a version closer to the original one. With an automatic method, restoration would be affordable for most pictures. Our work goes in that direction. In this article, we present a general algorithm for restoration of local-non-time-correlated (LNTC) defects based on morphological tools.
