概要 A method for removing film scratches in old video is
proposed. This method is realized as combination of spaciotemporal
exemplar-based inpainting and directional median
filtering. The spacio-temporal inpainting restores scratch areas
with image pixels in a similar undamaged image area in the same
and the adjacent frames. If such a similar image area exist, the
inpainting method works effectively, however, it does not always
exist. In this paper, a method to switch the spacio-temporal
inpaiting and a directional median filter is proposed to remove
film scratches. Here, if the matching error of inpainting is not
small enough, which means that a similar undamaged image area
does not exist in the neighborhood, the scratch area is restored
using the directional median filter. The directional median filter
performs one-dimensional median filtering in the direction of the
straight line component detected around the scratch. This
method works effectively, even if a similar undamaged image
area is not obtained. Computer simulations show the high
performance of the proposed method for actual video frames.
