On adaptive wavelet packets
Ricardo Lopes de Queiroz, K.R. Rao · 1993 IEEE International Symposium on Circuits and Systems · 2002
An algorithm is presented for fast implementation of time-varying wavelet packets maintaining perfect reconstruction throughout transitions. It is based on filter banks known as the extended lapped transforms in an association following the paths of a binary-tree. Methods for pruning or expanding the branches of the tree are presented, and a discussion on adaptation issues is given.>
