function dss = diffss(ss)
% DIFFSS Difference of scale space
% DSS=DIFFSS(SS) returns a scale space DSS obtained by subtracting
% consecutive levels of the scale space SS.
%
% In SIFT this function is used to compute the difference of
% Gaussian scale space from the Gaussian scale space of an image.
%
% See also GAUSSIANSS() PDF:SIFT.USER.SS.
