Discrete wavelet filtering is reversible (provided that
reversible filters are used), i.e. we can "analyze" a signal by
the so called analyzing filtering process and we could
reconstruct the original image from the filtered signal by a so
called synthesizing filtering process. Filtering could be done
in a multi-level way, where only the resultig lowpass-part of
one level of filtering is filtered again. When filtering images
(i.e. a 2D signal) this is done in an alternating fashion on
rows and columns of the lowpass-part of the image.
