Current sub-pixel motion estimation algorithm is time and memory-consuming when performing image compression and communication. So we propose a selective interpolation method for sub-pixel motion estimation. We applied selective interpolations after estimating a candidate for sub-pixel accuracy motion vector from the simplest mathematical model. According to simulation results, the proposed method attains nearly the same performance as the full-search for half-pixel motion estimation with much lower computational complexity.
