一、简介
基于matlab GUI形态学限速标志识别
二、源代码
function varargout = Mat5_2(varargin)
% MAT5_2 MATLAB code for Mat5_2.fig
% MAT5_2, by itself, creates a new MAT5_2 or raises the existing
% singleton*.
%
% H = MAT5_2 returns the handle to a new MAT5_2 or the handle to
% the existing singleton*.
%
% MAT5_2('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in MAT5_2.M with the given input arguments.
%
% MAT5_2('Property','Value',...) creates a new MAT5_2 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before Mat5_2_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to Mat5_2_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
%
% See also: GUIDE, GUIDATA, GUIHANDLES
