An adaptive and parallel scheme for hd video de-interlacing

It is very challenging to de-interlace HD videos in real time, as both high efficiency and low complexity should be fulfilled, which, however, are conflicting. This paper presents a de-interlacer to resolve the conflict specially for H.264 coded videos. It adapts to spatially and temporally local activities by making full use of the syntax element (SE) values in bit-streams, which give many hints of the motions and textures of video sequences. Accuracy analysis is also introduced to deal with the disparity between the SE values and the real motions and textures. The experimental results show the proposed de-interlacer provides better visual quality than common ones and can de-interlace 1080i sequences in real time on PCs.
