H.264-compatible coding of background soccer video using temporal subbands

• This paper presents an H.264-compatible temporal subband coding scheme for static background scenes of soccer video. We utilize orthonormal wavelet transforms to decompose a group of successive frames into temporal subbands. By exploiting the property of energy conservation of orthonormal wavelet transforms, we construct a rate distortion model for optimal bitrate allocation among different subbands. To take advantage of the high efficiency video codec H.264/AVC, we encode each subband with H.264/AVC Fidelity Range Extension (FRExt) intra-coding by assigning optimal bitrates. The experimental results show that our proposed coding scheme outperforms conventional video coding with H.264/AVC for both subjective and objective evaluations.
