On the implementation of nonseparable two-dimensional Haar wavelet transforms
P. Lenders, A. Sjostrom · IEEE Transactions on Signal Processing · 1999
We introduce a transformation to localize the equations defining the successive levels of the Mallat (1989) pyramid for two-dimensional (2-D) Haar wavelets. We propose a methodology for implementing these wavelet transforms in parallel architectures like systolic arrays. More specifically, we show that there is a perfect match between the wavelet algorithms and the multiphase multirate array (MPRA) architectures.
