function afine = AIDyadUp(beta,alfa,D,F,EF)
% AIDyadUp -- Average-Interpolating UpSampling Operator
%  Usage
%    afine = AIDyadUp(beta,alfa,D,F,EF)
%  Inputs
%    beta    coarse-scale block averages
%    alfa    detail corrections
%    D       degree of polynomial fit in average-interpolation
%    F       filter implementing average-interpolation
%    EF      edge filter of average-interpolation
%  Outputs
%    afine   fine-scale block averages
%
%  Description
%    Implements the Coarse-to-Fine phase of the average-interpolating
%    wavelet transform. Takes coarse scale block average and detail
%    corrections and synthesizes fine-scale block averages.
