Can anyone point me to literature that explains a quote from here : Why is a wavelet transform implemented as a filter bank?
So not all wavelets can be implemeted perfectly (invertible) with efficient filter banks. It is well known that discrete orthogonal wavelets cannot be real/symmetric/finite-length, except the Haar wavelet. Yet there exists a great deal of discrete wavelets that can be effciient on several signal/image/point cloud/mesh data.
