The fractional-pixel motion compensation is used in the H.264/AVC algorithm, in order to improve the coding efficiency of fractional-pixel displacement, an efficient cubic convolution interpolation (CCI) with four coefficients is proposed. In this paper, the detailed derivation of the CCI filter and using CCI with fractional-pixel displacement are presented. It is shown by computer simulation that the presented method substantially reduces the computation complexity and also increases the precision of the motion compensation.
