% adfig13 -- Adapt Figure 13: WaveJS Reconstructions from Noisy Data; S8 Wavelet
%
% A classical James-Stein shrinker applied in the wavelet domain
% to different resolution levels independently of one another.
%
% The results are noisier-looking than the results of the 
% nonlinear soft thresholding of wavelet coefficients.
