title = "Tree structures for time-frequency signal analysis",
abstract = "The popular orthonormal decomposition techniques such as block transforms and filter banks for multiresolution signal representation are unified. Their comparative performance results based on signal energy compaction are presented for image and AR(1) sources. It is observed that the filter banks with computationally efficient filtering algorithms and irregular tree structures, unequal bands, are potential competitors to the block transforms, particularly for image processing and coding applications.",
