摘要
Abstract
A novel video coding algorithm based on intraframe and interframe prediction of wavelet coefficients is described in this paper. A BZT (Block Zero Tree) coding scheme represents the position of zero coefficients block efficiently. For nonzero coefficients block, temporal redundancy is removed using MultiResolution Motion Estimation (MRME). The proposed algorithm improves the coding performance significantly over the baseline MRME technique. In addition, the computational complexity is further reduced.关键词
