Paper Abstract

As one important component in H.264 video encoder, interpolation of half and quarter pixels is also computational intensive. Compared to integer pixel motion estimation, "finer" interpolation provides better block match. However, this good motion compensation performance is obtained at the expense of increased complexity. Based on our previous work, this paper presents an improved fast and adaptive interpolation method that further reduces the complexity of video encoding process. Experimental results on typical video sequences demonstrate that the proposed method is able to increase encoder speed ranging from 10% to 22% compared with our previous work without any PSNR loss or bit rate increase.
