Based on the research of H.26L coding structure, a novel approach of image resampling in motion compensated prediction used cubic convolution interpolation instead of bilinear interpolation is proposed and conception of Adaptive Motion Accuracy is given. Compared with the bilinear interpolation in H.263, cubic convolution interpolation has its advantages. Then we realized the H.26L software codec based on cubic convolution interpolation. Implementation results show that cubic convolution interpolation is effective.
