设计一基于界面GUI的图像处理软件综合设计
第1章综合设计
1.1设计目的
综合运用MATLAB工具箱实现图像处理的GUI程序设计，利用MATLAB图像处理工具箱，设计和实现自己的Photoshop。
1.2设计内容
基于界面GUI的图像处理软件综合设计（基于Matlab或者VC++）：
实现功能：
包括图像的读取、存储、显示、加噪、去噪、增强、边缘检测、图像分割、离散傅立叶变换、小波变换、特征提取、目标识别、彩色图像处理等功能（可自己任意设计、增减功能）
1.3题目分析
利用matlab的GUI程序设计一个简单实用的图像处理程序。
该程序应具备图像处理的常用功能，以满足用户的使用。
现设计程序有以下基本功能：
1）图像的读取和保存；
2）设计菜单栏，让用户能调用和隐藏相关功能键；
3）设计图形用户界面，让用户能够对图像进行任意的亮度和对比度变化调整，显示和对比变换前后的图像；
4）设计图形用户界面，让用户能够用鼠标选取图像感兴趣区域，显示和保存该选择区域；
5）图像直方图统计和直方图均衡，要求显示四种直方图统计，比较直方图均衡后的效果；
6）能对图像加入各种噪声，并通过几种滤波算法实现去噪并显示结果；
7）特殊处理，实现底片效果、边缘效果；
8）额外功能，如撤销、还原。
1.4总体设计
图1
软件的总体设计界面布局如上图所示，主要分为2个部分：
显示区域与操作区域。
显示区域：
显示载入原图，以及通过处理后的图像。
操作区域：
通过功能键实现对图像的各种处理。
在截图中可见，有一系列常用功能按键如“灰度处理”、“截图”、“撤销”、“还原”等等；设计完成后运行的软件界面如下：
图2
与图1相比，运行后的界面更为简洁。
利用“编辑”菜单可调出相应的功能键。
第2章具体设计
2.1菜单栏设计。
通过MenuEditor创建如下菜单，通过以下菜单来控制显示或隐藏功能按键
图3
以“编辑”菜单中“普通处理”中的“直方图统计”为例说明实现用户界面功能键“直方图统计”的显示与隐藏。
通过设置“直方图统计”功能键对应的句柄tongjiupn中的“Visible”属性的开关来实现该功能键的显示隐藏。
其他同理。
实现该功能的程序段如下：
functiontongji_Callback（hObject,eventdata,handles）
set（handles.tongjiupn,'Visible','on'）;
ifstrcmp（get（gcbo,'Checked'）,'on'）
set（handles.tongjiupn,'Visible','on'）;
set（gcbo,'Checked','off'）;
set（handles.tongjiupn,'Visible','off'）;
else
set（gcbo,'Checked','on'）;
end
2.2图像的读取、保存和退出
利用“文件”菜单中的“打开文件”、“保存”、“退出”分别实现图片的读取、保存和退出。
2.2.1图像的读取
matlab中，通过uigetfile选择相应路径打开的图像；通过imread（file）读取选中的图像；最后，通过imshow（x）在显示区域上显示图像。
其实现程序如下：
functionopenfile_Callback（hObject,eventdata,handles）
[filename,pathname]=uigetfile（{'*.jpg';'*.bmp';'*.tif';'*.*'},'载入图像'）;
ifisequal（filename,0）||isequal（pathname,0）
errordlg（'没有选中文件','出错'）;
return;
else%图像读取
file=[pathname,filename];
globalS%设置一个全局变量S，保存初始图像路径，以便之后的还原操作
S=file;
x=imread（file）;
set（handles.axes1,'HandleVisibility','ON'）;
axes（handles.axes1）;
imshow（x）;
set（handles.axes1,'HandleVisibility','OFF'）;
axes（handles.axes2）;
imshow（x）;
handles.img=x;
guidata（hObject,handles）;
end
2.2.2图像的保存
matlab中，通过uiputfile选择图像文件保存的路径与格式；然后，通过imwrite实现对图像的保存。
其实现程序如下：
functionsave_Callback（hObject,eventdata,handles）
[sfilename,sfilepath]=uiputfile（{'*.jpg';'*.bmp';'*.tif';'*.*'},'保存图像文件','untitled.jpg'）;
if~isequal（[sfilename,sfilepath],[0,0]）
sfilefullname=[sfilepath,sfilename];
imwrite（handles.img,sfilefullname）;
else
msgbox（'你按了取消键','保存失败'）;
end
2.2.3图像的退出
functionexit_Callback（hObject,eventdata,handl
