用MATLAB的GUI程序设计一个具备图像边缘检测功能的用户界面该设计程序有以下基本功能
1图像的读取和保存。
2设计图形用户界面让用户对图像进行彩色图像到灰度图像的转换并显示原图和灰度图像。
3设计图形用户界面让用户能够根据需要来选择边缘检测算子即选择边缘检测的方法。
4设计图形用户界面让用户能够自行设定检测的阈值和方向。
5显示边缘检测后的图像并与原图和灰度图像进行对比。
【实验步骤】
1、建立菜单选项包括“文件”打开、保存、退出、“检测方法”sobel、prewitt、roberts、canny和“帮助”。 建立3个坐标轴对象用于显示原始图像、灰度图像和边缘检测后的图像。
建立1个按钮用于将原始图像转换为灰度图像。
建立1个文本编辑框用于输入数据。 建立菜单选项包括“文件”打开、保存、退出、“检测方法”sobel、prewitt、roberts、canny和“帮助”。
五个静态文本框的string属性分别为“原图”、“灰度图像”、“检测图像”、“设定阈值”和“检测方向”。
三个坐标轴的Tag标识分别为original_image、gray_image、test_image。
按钮控件的string属性为“灰度转换”Tag标识为rgbtogray。
文本编辑框的Tag标识为thresh_value。
列表框的string属性为horizontal、vertical、bothTag标识为direction。
编写代码完成程序中的变量赋值、输入、输出等工作打开对应文件在对应函数位置添加如下程序其他代码不变。
function varargout m240531(varargin)
% M240531 MATLAB code for m240531.fig
% M240531, by itself, creates a new M240531 or raises the existing
% singleton*.
%
% H M240531 returns the handle to a new M240531 or the handle to
% the existing singleton*.
%
% M240531(CALLBACK,hObject,eventData,handles,...) calls the local
% function named CALLBACK in M240531.M with the given input arguments.
%
% M240531(Property,Value,...) creates a new M240531 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before m240531_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to m240531_OpeningFcn via varargin.
%
% *See GUI Options on GUIDEs Tools menu. Choose GUI allows only one
% instance to run (singleton).
