A Fast Efficient Fractional-Pixel Displacement for H.264/AVC Motion Compensation
AINA Workshops（2014）
摘要
The fractional-pixel displacement has been proposed in the motion compensation prediction for the H.264/AVC algorithm. In this paper, a cubic convolution interpolation filter with four coefficients is presented to improve the coding efficiency of fractional-pixel displacement for H.264/AVC. Experimental results show that the proposed cubic convolution interpolation filter can be used to increase the fractional-pixel precisions and also obtain a superior performance for motion compensation.
