% evaluate_nbr_bits_wavelets - evaluate the number of bits to code a wavelet transform
%
%   nbr_bits = perform_shannon_estimation_wavelets(MW, Jmin, T);
%
%   MW is the wavelet transform,
%   Jmin is the minimum scale of the transform,
%   T is the quantification step,
%   nbr_bit is a lower bound (Shanon entropy bound) on the number 
%       of bits needed to code the wavelet image.
