function varargout = svca4_imageTACGui(varargin)
% SVCA4_IMAGETACGUI MATLAB code for svca4_imageTACGui.fig
%      SVCA4_IMAGETACGUI, by itself, creates a new SVCA4_IMAGETACGUI or raises the existing
%      singleton*.
%
%      H = SVCA4_IMAGETACGUI returns the handle to a new SVCA4_IMAGETACGUI or the handle to
%      the existing singleton*.
%
%      SVCA4_IMAGETACGUI('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in SVCA4_IMAGETACGUI.M with the given input arguments.
%
%      SVCA4_IMAGETACGUI('Property','Value',...) creates a new SVCA4_IMAGETACGUI or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before svca4_imageTACGui_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to svca4_imageTACGui_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
