Abstract :
Twin-lens telecine flicker is considered as a special type of artefact in film-to-video conversions. It is introduced by telecine equipment using separate optic light paths to register each of the two fields of a line-interlaced video frame. Motion estimation and compensation algorithms suitable for the elimination of this type of artefact are developed. Their application achieves considerable improvement in picture quality both subjectively and in terms of measured mean-square error
