摘要

This paper discusses the construction of perfect reconstruction filter banks using morphological operators, Two concrete examples are given: (i) the morphological Haar wavelet, and (ii) a wavelet decomposition obtained from the lifting scheme which has the nice property that local maxima are being preserved.
