Abstract

This paper introduces a new method of converting interlaced video to a progressively scanned video. The missing pixel values of the interlaced sequence are interpolated from past fields according to motion vectors found between the present and past. Hierarchical block-matching motion estimation is used in finding these motion vectors. This approach gives improved results over conventional de-interlacing methods such as median filtering and linear spatial interpolation.
