Lung-Jen Wang, Wen-Ming Tai · American Journal of Signal Processing · 2018
The fractional-pixel motion estimation is used accurately for motion vector prediction in the H.264/AVC video coding. Based on the linear prediction and a small diamond search algorithm, a fast fractional-pixel search algorithm is proposed in this paper. The proposed method substantially solves the complexity of the calculation of the fractional-pixel motion estimation needed in the H.264/AVC video coding if the image resolution is increased. Finally, experimental results show that the proposed algorithm is superior in performance and reduces around 60% computations for the fractional-pixel calculations.
