% FastUDWTSynthesis -- Synthesis operator for Undecimated DWT (TI)
%  Usage:
%	x = FastUDWTSynthesis(wcb, n, scale, qmf, scign)
%  Inputs:
%	wcb	the coefs, a structure array
%	scale	the coarsest decomposition scale
%	qmf	the quadrature mirror filter
%	scign   the number of detail scales to be ignored in the reconstruction
%  Outputs:
%	x	the synthesized signal, a column vector
