Title: An Efficient Method for Accuracy Motion Estimation
Abstract: This article proposes a new algorithm applicable to H.264 based on motion vector coding length and high-pixel accuracy filter operator instead of linear interpolation. After half-pixel accuracy motion estimation, a high accuracy motion estimation can be calculated with the intermediate results. This algorithm can achieve high accuracy estimation and compensation while decreasing algorithm complexity. The computer simulation results show that when the new proposed algorithm for 1/8-pixel accuracy is used in QCIF, CIF, CCIR format pictures, total computing time reduces more than 20% and computing time used for fractional-pixel motion estimation reduces more than 50% while coding length only increases less than 10% and PSNR-Y is approximately equal.
