The high computation load of fractional-pixel motion estimation (FME) cannot be ignored although it improves visibly the PSNR performance after the integer-pixel motion estimation (IME) process. Most of conventional FME methods must include the interpolation procedure to form the fractional-pixel points from the integer-pixel information. However, the interpolating requires a considerable memory usage and any amount of processing time. In this paper, therefore, we propose interpolation-free fractional-pixel position prediction techniques based on Bezier curve and post the results of the simulation which show a remarkable performance improvement compared to the existing FME methods in terms of PSNR.
