matlab-GUI整理-图形处理
matlab-GUI—菜单栏应用
- 新建空白GUIDE，打开菜单编辑器，添加修改菜单栏名字
-
打开编辑器，编写菜单栏下各标记函数，编辑器完成后，就可生成效果图了
- 填充程序如下，其中test.jpg需要全部修改为需要处理的图，并将m文件、fig文件和图片放置当前路径，即可运行图片处理程序了
function varargout = Digital_figure_prosses(varargin) % DIGITAL_FIGURE_PROSSES MATLAB code for Digital_figure_prosses.fig % DIGITAL_FIGURE_PROSSES, by itself, creates a new DIGITAL_FIGURE_PROSSES or raises the existing % singleton*. % % H = DIGITAL_FIGURE_PROSSES returns the handle to a new DIGITAL_FIGURE_PROSSES or the handle to % the existing singleton*. % % DIGITAL_FIGURE_PROSSES('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in DIGITAL_FIGURE_PROSSES.M with the given input arguments. % % DIGITAL_FIGURE_PROSSES('Property','Value',...) creates a new DIGITAL_FIGURE_PROSSES or raises the % existing singleton*.
