-% [PYR, INDICES, STEERMTX, HARMONICS] = buildSFpyr(IM, HEIGHT, ORDER, TWIDTH)
-%
-% Construct a steerable pyramid on matrix IM, in the Fourier domain.
-% This is similar to buildSpyr, except that:
-%
-%    + Reconstruction is exact (within floating point errors)
-%    + It can produce any number of orientation bands.
-%    - Typically slower, especially for non-power-of-two sizes.
-%    - Boundary-handling is circular.
-%
-% HEIGHT (optional) specifies the number of pyramid levels to build. Default
-% is maxPyrHt(size(IM),size(FILT));
-%
-% The squared radial functions tile the Fourier plane, with a raised-cosine
-% falloff.  Angular functions are cos(theta-k\pi/(K+1))^K, where K is
-% the ORDER (one less than the number of orientation bands, default= 3).
-%
-% 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).
-%
-% 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.
-% See the function STEER for a description of STEERMTX and HARMONICS.

-% See http://www.cns.nyu.edu/~eero/STEERPYR/ for more
