Encode_Image.m

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