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