#
#  This biorthogonal wavelet filter bank is designed as a spline
#  variant with less dissimilar lengths.  Originally published by
#  Cohen et al., this filter bank has seen widespread use in
#  image-processing applications since it was used by Antonini, et al.
#
#  Permitted boundary methods:
#    symmetric extension, periodic extension
