%--------------------------------------------------------------------------
% a short description:
% input a gray fingerprint picture return the character vector of it.
% The main function calls :img=preprocessing(A);[ii,jj]=centralizing(A);
% Sam=samfun(r,R,n,N1);The following list gives a brief description:
%--------------------------------------------------------------------------
%M-file list:
%
% preprocessing.m:(be called by main function pic2vec)
% preprocess the picture including:Wiener filter;
% meddle value filter, change a gray picture to a
% binary one and then get the skeleton.
% centralizing.m: (be called by main function pic2vec)
% input the source picture output the core point of
% the fingerprint.Gabor filter is used in this function,
% and it call gabor2d_sub.m to generate a Gabor filter.
% it also call varpic.m to calculate a variance picture.
% samfun.m: (be called by main function pic2vec)
% generate the sample pattern automatically, which is
% used to sample the fingerprint.
% gabor2d_sub: (be called by centralizing.m)
% get gabor filter.
% varpic.m: (be called by centralizing.m)
% calculate variance picture
%--------------------------------------------------------------------------
% Globl parameter:
%
% the following parameter is used to define the sample pattern
% all these parameter is extremely correlate to the application
% and can be decided by experiment
% r=radius of smallest circle(default 10)
% R=radius of the biggest circls(default 160)
% n=number of the circle(default 7)
% N1=first circle's sample N1 times(default 4)
