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

% See also: GUIDE, GUIDATA, GUIHANDLES
