In this paper, a fast one-pass processing method with an efficient architecture is proposed for motion compensated frame interpolation (MCFI) in high-definition (HD) videos. Unlike previous works involving high complexity, complicated time-consuming iterations, and less practicability, the proposed method adopts one-pass and low-complexity concept. The proposed method operates a modified fast full-search algorithm, multi-level successive eliminate algorithm (MSEA), in a raster scan order as in the usual block-based
