Image processing based on MATLAB GUI image gray scale + scaling + storage processing

function varargout = GUI_TEST(varargin)
% GUI_TEST MATLAB code for GUI_TEST.fig
%      GUI_TEST, by itself, creates a new GUI_TEST or raises the existing
%      singleton*.
%
%      H = GUI_TEST returns the handle to a new GUI_TEST or the handle to
%      the existing singleton*.
%
%      GUI_TEST('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in GUI_TEST.M with the given input arguments.
%
%      GUI_TEST('Property'.'Value',...). creates anew GUI_TEST or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before GUI_TEST_OpeningFcn gets called.  An
%      unrecognized property name orinvalid value makes property application % stop. All inputs are passed to GUI_TEST_OpeningFcn via varargin. % % *See GUI  Options on GUIDE's Tools menu.  Choose "GUI allows only one % instance to run (singleton)".
