perform_steerable_transform.m

小波提升算法的实现

function y = perform_steerable_transform(x, Jmin,options)

% perform_steerable_transform - steerable pyramidal transform
%
%   y = perform_steerable_transform(x, Jmin,options);
%
%   This is just a convenient wrapper to the original steerable 
%   matlab toolbox of Simoncelli that can be downloaded from
%       http://www.cns.nyu.edu/~eero/STEERPYR/
%
%   It provide a simpler interface that directly output a cell
%   array of images. Usage :
%
%   M = load_image('lena');
%   MS = perform_steerable_transform(M, 3); % synthesis
%   M1 = perform_steerable_transform(MS);   % reconstruction
