convert_wavelets2list.m

小波提升算法的实现

function y = convert_wavelets2list(x, Jmin, Jmax, pack_imagettes);

% convert_wavelets2list - convert a wavelet transform into a cell array.
%
%	y = convert_wavelets2list(x, Jmin, Jmax);
%
%   If x is a wavelet transform, then x is a cell array (a list)
%       of cell array. y{1} is a cell array containing
%       H/V/D quadrant of the transform at finest scale (Jmax), 
%       y{2} contains the quadrant at scale Jmax-1, etc.
%       y{end} contains the low scale decomposition.
%   If x is a call array, then it compute the inverse decomposition.
