一、简介

基于matlab GUI sobel+prewit+canny算法图像边缘检测

二、源代码

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 a new 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)".

% --- Executes just before guipic is made visible.
function guipic_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% varargin   command line arguments to guipic (see VARARGIN)

% Choose default command line output for guipic
handles.output = hObject;

% Update handles structure
guidata(hObject, handles);

% UIWAIT makes guipic wait for user response (see UIRESUME)
% uiwait(handles.figure1);


% --- Outputs from this function are returned to the command line.
function varargout = guipic_OutputFcn(hObject, eventdata, handles) 
% varargout  cell array for returning output args (see VARARGOUT);
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% Get default command line output from handles structure
varargout{1} = handles.output;


% --- Executes on button press in ok.
function ok_Callback(hObject, eventdata, handles)
% hObject    handle to ok (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
global im
%选择图片路径
[filename,pathname]=...
    uigetfile({‘*.jpg‘;‘*.bmp‘;‘*.gif‘},‘选择图片‘);
%合成路径加文件名
str=[pathname filename];
%读取图片
im=imread(str);
%使用第一个AXES
axes(handles.axes1);
%显示图片
imshow(im);

% --- Executes on button press in pushbutton2.
function pushbutton2_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton2 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
close(gcf)


% --- Executes when selected object is changed in uipanel1.
function uipanel1_SelectionChangeFcn(hObject, eventdata, handles)
% hObject    handle to the selected object in uipanel1 
% eventdata  structure with the following fields (see UIBUTTONGROUP)
%	EventName: string ‘SelectionChanged‘ (read only)
%	OldValue: handle of the previously selected object or empty if none was selected
%	NewValue: handle of the currently selected object
% handles    structure with handles and user data (see GUIDATA)
global im
%拿到选择按钮的名称
str=get(hObject,‘string‘);
axes=(handles.axes1);
