Abstract
- In wavelet-based video coding with motion-compensated lifting, efficient compression is achieved by exploiting motion-compensated temporal filtering (MCTF). The performance of a 3D wavelet video codec is greatly dependent on the efficient of MCTF. In this paper, an adaptive motion-compensated temporal filter scheme is proposed for wavelet video coding. Our method focused to control the level number of the temporal decomposition by detecting the number of the un-connection pixels in low-pass frame to avoid the inefficiency of MCTF while scene changing quickly. Moreover, this method has most useful features of predictive wavelet codecs, such as multiple reference frame and bi-directional prediction. Our experimental results show that, compared with the conventional MCTF, the proposed scheme has better coding performance for most sequences. [ABSTRACT FROM AUTHOR]
