Flicker reduction in old films

This paper deals with the reduction of flicker in old films. This artifact appears as global, quick and random variations of the luminance and contrast between consecutive frames of a sequence. Initially, we present a method based on the correction of mean and variance parameters of the sequence. However, although this method reduces mean and variance variation between frames, it does not yield good visual results. Finally, an algorithm based on the histogram matching is proposed. This method provides much better visual results.
