Image edge detection based on MATLAB GUI Sobel + Prewit + Canny algorithm image edge detection

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