一、简介

1 课题介绍
本设计为基于MATLAB的火灾检测系统。结合火焰是实时动态跳跃的，采用面积增长率，角点和圆形度三个维度相结合的方式判断是否有火焰。该设计测试对象为视频，通过下一帧和上一帧的差异发现是否有火情。本设计带有一个人机交互式GUI界面，界面友好。是个不错的选题。
2 算法流程
结合火焰的面积增长率，角点和圆形度三个维度综合判断。并且得出每帧图像火焰部分的该三个参数，实时显示在GUI上。

二、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)".
