% mefig605 -- Residuals from Segmentation Pursuit, object "Bumps"
%
% Here we do ten iterations of segmentation pursuit on object Bumps.
% We show the successive residuals at the first ten stages.
%
% WARNING: unless you have the appropriate .MEX file installed,
% or are using a wickedly fast machine, this can take hours.
%
% Note: this depend on your having already run mefig604.
