摘要：
A new family of wavelet transforms (WTs) based on the extended lapped transform (ELT) is introduced. A new optimisation criterion for the ELT butterfly angles is presented, leading to ELT-based WTs with virtually the same performance but a much lower computational complexity than the standard maximally-regular WTs.
