| Abstract: |
In this paper, a four field local motion compensated de-interlacing method is proposed to solve the occlusion and true motion vector problems of motion compensated de-interlacing. The proposed de-interlacing method consists of four field motion estimation, 5+5 taps ELA, and intra/MC macroblock mode decision. True motion vectors can be obtained by the four field motion estimation and its matching criterion is extended by the characteristic of interlace-scanned field. The mode decision could detect an occlusive macroblock and choose its best mode. Hardware implementation has been considered. The results show that the proposed de-interlacing method can produce images compensated by great majority of the original fields with little intra-field interpolation, and the subjective view results are jag-free and flicker-free high quality images. |
