An Adaptive True Motion Estimation Algorithm for Frame Rate Conversion of High Definition Video

Frame Rate Up-Conversion (FRUC) is necessary for displaying low frame rate video signals on high frame rate flat panel displays. This paper proposes an adaptive true Motion Estimation (ME) algorithm for FRUC of High Definition video formats. The proposed ME algorithm produces similar quality results with less number of calculations or better quality results with similar number of calculations compared to 3D Recursive Search true ME algorithm by adaptively using optimized sets of candidate search locations and several computational complexity reduction techniques.
