Hideaki Kimata, M. Kitahara, Yoshiyuki Yashima · 2003
Fractional pel motion compensation generally improves coding efficiency due to more precise motion accuracy and low path filtering effect in generating image at fractional pel positions. In H.264, quarter pel motion compensation is applied, where image at half pel position is generated by 6 tap Wiener filter. And the adaptive interpolation filter technique, which adaptively changes filter characteristics for half pel positions have been proposed. That technique also changes image at quarter pel positions, so it can be exploited to extent motion accuracy to be more precise. In this paper, 3D motion vector coding (3DMVC) technique with block base adaptive interpolation filter (BAIF) is proposed. This paper also demonstrates the proposed method achieves filter data is successfully integrated into motion vector coding and outperforms the normal H.264.
