% NOISECOMP - Function for denoising an image
%
% function cleanimage = noisecomp(image, k, nscale, mult, norient, softness)
%
% Parameters:
% k - No of standard deviations of noise to reject 2-3
% nscale - No of filter scales to use (5-7) - the more scales used
% the more low frequencies are covered
% mult - multiplying factor between scales (2.5-3)
% norient - No of orientations to use (6)
% softness - degree of soft thresholding (0-hard 1-soft)
%
% For maximum processing speed the input image should have a size that
% is a power of 2.
%
% The convolutions are done via the FFT. Many of the parameters relate
% to the specification of the filters in the frequency plane.
% The parameters are set within the file rather than being specified as
% arguments because they rarely need to be changed - nor are they very
% critical.
