matlab gui设置背景颜色问题。

Posted 2023-05-10

比如我要设置一个pushbutton的背景颜色,语句是set(handles.pushbutton,'background','r');这是设置成红色，要是想设置成RGB（1,1,1）对应的颜色该怎么设置？？set(hObject,'background','[1，1，1]')不对，该是什么格式呢？？

参考技术A set(handles.pushbutton1,'backgroundcolor',[1,1,1]);追问

这样试过，之前试的不好使，刚才试又好使了。。。。

本回答被提问者采纳 参考技术B 这个直接双击那个按钮就可以选择根本不用写代码

图像识别基于帧差法和颜色空间实现火灾检测matlab源码GUI

1 帧差法原理

帧差法的实现非常简单：

如图可见，由目标运动引起的运动变化区域包括运动目标在前后两帧中的共同位置(图中黑色区域)、在当前帧中新显露出的背景区域和新覆盖的背景区域三部分。

2 源代码

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