#  Daubechies.Diagonal.2x2.4.vfb
#
#  Vector filter bank constructed by placing scalar Daubechies orthonormal
#  wavelet coefficients on the diagonal of the vector-filter-bank
#  coefficient matrices, causing an identical scalar wavelet transform to be
#  performed on each vector component individually.  Use the length-4
#  Daubechies filters.
