perform_haar_transform_slow.m

小波提升算法的实现

function y = perform_haar_transform_slow(x, Jmin, dir);

% perform_haar_transform - compute a wavelet haar transform
%
% y = perform_haar_transform(x, Jmin, dir);
%
%   This is the non-optimized Matlab version.
%   TODO : code inverse transform (the mex version does implement it).
