Abstract: Based on motionlessness detection and motion vector prediction, an effective motion estimation algorithm combining local full search and down-sampling is proposed. It accelerates the search speed and maintains high search accuracy. The motion estimation algorithm is applied to the Frame Rate Up-conversion(FRUC) system. Experimental results show that the proposed algorithm not only reduces the calculation complexity, but also maintains satisfactory visual quality and PSNR.

Key words: motionlessness detection, motion vector prediction, down-sampling, Frame Rate Up-conversion(FRUC)
