-% RES = reconSFpyr(PYR, INDICES, LEVS, BANDS, TWIDTH)
-%
-% Reconstruct image from its steerable pyramid representation, in the Fourier
-% domain, as created by buildSFpyr.
-%
-% PYR is a vector containing the N pyramid subbands, ordered from fine
-% to coarse.  INDICES is an Nx2 matrix containing the sizes of
-% each subband.  This is compatible with the MatLab Wavelet toolbox.
-%
-% LEVS (optional) should be a list of levels to include, or the string
-% 'all' (default).  0 corresonds to the residual highpass subband.  
-% 1 corresponds to the finest oriented scale.  The lowpass band
-% corresponds to number spyrHt(INDICES)+1.
-%
-% BANDS (optional) should be a list of bands to include, or the string
-% 'all' (default).  1 = vertical, rest proceeding anti-clockwise.
-%
-% TWIDTH is the width of the transition region of the radial lowpass
-% function, in octaves (default = 1, which gives a raised cosine for
-% the bandpass filters).
-
-%%% MODIFIED VERSION, 7/04, uses different lookup table for radial frequency!
