摘要
研究双正交滤波与其多相矩阵之间的关系,证明滤波多相矩阵的三角分解对应于滤波的提升和对偶提升的定理,井用之构造双正交滤波和正交滤波.
The relation between the lifting coefficients and the polyphase matrix for the biorthogonal filters is studied. A theorem that the triangular decomposition for filters corresponding to the lifting and dual-lifting of them is proved, and by which orthogonal and biorthogonal filters are constructed respectively.
