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